Release v7.10.1

* fix(theme): the minor typo error

* fix(style): make lv_style_reset work with zerod memory

* fix(theme): fix the memory leak when lv_theme_xxx_init is called twice

due to inited variable forget to set to 1

* fix(theme): empty theme should call lv_obj_refresh_style too

and remove lv_obj_clean_style_list since the same thing is
already done in the common code(clear_styles)

+Complete rework of LVGL's draw engine to use "masks" for more advanced and higher quality graphical effects.
+A possible use-case of this system is to remove the overflowing content from the rounded edges.
+It also allows drawing perfectly anti-aliased circles, lines, and arcs.
+Internally, the drawings happen by defining masks (such as rounded rectangle, line, angle).
+When something is drawn the currently active masks can make some pixels transparent.
+For example, rectangle borders are drawn by using 2 rectangle masks: one mask removes the inner part and another the outer part.
+
+The API in this regard remained the same but some new functions were added:
+- `lv_img_set_zoom`: set image object's zoom factor
+- `lv_img_set_angle`: set image object's angle without using canvas
+- `lv_img_set_pivot`: set the pivot point of rotation
+
+The new drawing engine brought new drawing features too. They are highlighted in the "style" section.
+
+### New style system
+The old style system is replaced with a new more flexible and lightweighted one.
+It uses an approach similar to CSS: support cascading styles, inheriting properties and local style properties per object.
+As part of these updates, a lot of objects were reworked and the APIs have been changed.
+
+- more shadows options: *offset* and *spread*
+- gradient stop position to shift the gradient area and horizontal gradient
+- `LV_BLEND_MODE_NORMAL/ADDITIVE/SUBTRACTIVE` blending modes
+- *clip corner*: crop the content on the rounded corners
+- *text underline* and *strikethrough*
+- dashed vertical and horizontal lines (*dash gap*, *dash_width*)
+- *outline*: a border-like part drawn out of the background. Can have spacing to the background.
+- *pattern*: display and image in the middle of the background or repeat it
+- *value* display a text which is stored in the style. It can be used e.g. as a lighweighted text on buttons too.
+- *margin*: similar to *padding* but used to keep space outside of the object
+
+Read the [Style](https://docs.littlevgl.com/v7/en/html/overview/style.html) section of the documentation to learn how the new styles system works.
+
+### GPU integration
+To better utilize GPUs, from this version GPU usage can be integrated into LVGL. In `lv_conf.h` any supported GPUs can be enabled with a single configuration option.
+
+Right now, only ST's DMA2D (Chrom-ART) is integrated. More will in the upcoming releases.
+
+### Renames
+The following object types are renamed:
+- sw -> switch
+- ta -> textarea
+- cb -> checkbox
+- lmeter -> linemeter
+- mbox -> msgbox
+- ddlist -> dropdown
+- btnm -> btnmatrix
+- kb -> keyboard
+- preload -> spinner
+- lv_objx folder -> lv_widgets
+- LV_FIT_FILL -> LV_FIT_PARENT
+- LV_FIT_FLOOD -> LV_FLOOD_MAX
+- LV_LAYOUT_COL_L/M/R -> LV_LAYOUT_COLUMN_LEFT/MID/RIGHT
+- LV_LAYOUT_ROW_T/M/B -> LV_LAYOUT_ROW_TOP/MID/BOTTOM
+
+### Reworked and improved object
+- `dropdown`: Completely reworked. Now creates a separate list when opened and can be dropped to down/up/left/right.
+- `label`: `body_draw` is removed, instead, if its style has a visible background/border/shadow etc it will be drawn. Padding really makes the object larger (not just virtually as before)
+- `arc`: can draw bacground too.
+- `btn`: doesn't store styles for each state because it's done naturally in the new style system.
+- `calendar`: highlight the pressed datum. The used styles are changed: use `LV_CALENDAR_PART_DATE` normal for normal dates, checked for highlighted, focused for today, pressed for the being pressed. (checked+pressed, focused+pressed also work)
+- `chart`: only has `LINE` and `COLUMN` types because with new styles all the others can be described. LV_CHART_PART_SERIES sets the style of the series. bg_opa > 0 draws an area in LINE mode. `LV_CHART_PART_SERIES_BG` also added to set a different style for the series area. Padding in `LV_CHART_PART_BG` makes the series area smaller, and it ensures space for axis labels/numbers.
+- `linemeter`, `gauge`: can have background if the related style properties are set. Padding makes the scale/lines smaller. scale_border_width and scale_end_border_width allow to draw an arc on the outer part of the scale lines.
+- `gauge`: `lv_gauge_set_needle_img` allows use image as needle
+- `canvas`: allow drawing to true color alpha and alpha only canvas, add `lv_canvas_blur_hor/ver` and rename `lv_canvas_rotate` to `lv_canvas_transform`
+- `textarea`: If available in the font use bullet (`U+2022`) character in text area password
+
+### New object types
+- `lv_objmask`: masks can be added to it. The children will be masked accordingly.
+
+### Others
+- Change the built-in fonts to [Montserrat](https://fonts.google.com/specimen/Montserrat) and add built-in fonts from 12 px to 48 px for every 2nd size.
+- Add example CJK and Arabic/Persian/Hebrew built-in font
+- Add ° and "bullet" to the built-in fonts
+- Add Arabic/Persian script support: change the character according to its position in the text.
+- Add `playback_time` to animations.
+- Add `repeat_count` to animations instead of the current "repeat forever".
+- Replace `LV_LAYOUT_PRETTY` with `LV_LAYOUT_PRETTY_TOP/MID/BOTTOM`
+
+### Demos
+- [lv_examples](https://github.com/littlevgl/lv_examples) was reworked and new examples and demos were added
+
+### New release policy
+- Maintain this Changelog for every release
+- Save old major version in new branches. E.g. `release/v6`
+- Merge new features and fixes directly into `master` and release a patch or minor releases every 2 weeks.
+
+### Migrating from v6 to v7
+- First and foremost, create a new `lv_conf.h` based on `lv_conf_template.h`.
+- To try the new version it suggested using a simulator project and see the examples.
+- If you have a running project, the most difficult part of the migration is updating to the new style system. Unfortunately, there is no better way than manually updating to the new format.
+- The other parts are mainly minor renames and refactoring as described above.

-## Porting
-In the most sime case you need 4 things:
-1. Call `lv_tick_inc(1)` in every millisecods in a Timer or Task
-2. Register a function which can copy a pixel array to an area of the screen
-3. Register a function which can read an input device. (E.g. touch pad)
-4. Call `lv_task_handler()` periodically in every few milliseconds ()

-## Project set-up
-1. Clone or download the lvgl repository: `git clone  https://github.com/littlevgl/lvgl.git`
-2. Create project with your prefered IDE and add the *lvgl* folder
-3. Copy *lvgl/lv_conf_templ.h* as *lv_conf.h* next to the lvgl folder
-4. In the *_conf.h files delete the first `#if 0` and its `#endif`. Let the default configurations at first.
-5. In your *main.c*: #include "lvgl/lvgl.h"   
-6. In your *main function*:
-   * lvgl_init();
-   * tick, display and input device initialization (see above)
-7. To **test** create a label: `lv_obj_t * label = lv_label_create(lv_scr_act(), NULL);`  
-8. In the main *while(1)* call `lv_task_handler();` and make a few milliseconds delay (e.g. `my_delay_ms(5);`) 
-9. Compile the code and load it to your embedded hardware

+# Coding style
+
+## File format
+Use [lv_misc/lv_templ.c](https://github.com/lvgl/lvgl/blob/master/src/lv_misc/lv_templ.c) and [lv_misc/lv_templ.h](https://github.com/lvgl/lvgl/blob/master/src/lv_misc/lv_templ.h)
+
+## Naming conventions
+* Words are separated by '_'
+* In variable and function names use only lower case letters (e.g. *height_tmp*)
+* In enums and defines use only upper case letters (e.g. *e.g. MAX_LINE_NUM*)
+* Global names (API):
+  * starts with *lv*
+  * followed by module name: *btn*, *label*, *style* etc.
+  * followed by the action (for functions): *set*, *get*, *refr* etc.
+  * closed with the subject: *name*, *size*, *state* etc.
+* Typedefs
+  * prefer `typedef struct` and `typedef enum` instead of  `struct name` and `enum name`
+  * always end `typedef struct` and `typedef enum` type names with `_t`
+* Abbreviations:
+  * Only words longer or equal than 6 characters can be abbreviated.
+  * Abbreviate only if it makes the word at least half as long
+  * Use only very straightforward and well-known abbreviations (e.g. pos: position, def: default, btn: button)
+
+## Coding guide
+* Functions:
+  * Try to write function shorter than is 50 lines
+  * Always shorter than 200 lines (except very straightforwards)
+* Variables:
+  * One line, one declaration (BAD: char x, y;)
+  * Use `<stdint.h>` (*uint8_t*, *int32_t* etc)
+  * Declare variables where needed (not all at function start)
+  * Use the smallest required scope
+  * Variables in a file (outside functions) are always *static*
+  * Do not use global variables (use functions to set/get static variables)
+
+## Comments
+Before every function have a comment like this:
+
+```c
+/**
+ * Return with the screen of an object
+ * @param obj pointer to an object
+ * @return pointer to a screen
+ */
+lv_obj_t * lv_obj_get_scr(lv_obj_t * obj);
+```
+
+Always use `/* Something */` format and NOT `//Something`
+
+Write readable code to avoid descriptive comments like:
+`x++; /* Add 1 to x */`.
+The code should show clearly what you are doing.
+
+You should write **why** have you done this:
+`x++; /*Because of closing '\0' of the string */`
+
+Short "code summaries" of a few lines are accepted. E.g. `/*Calculate the new coordinates*/`
+
+In comments use \` \` when referring to a variable. E.g. ``/*Update the value of `x_act`*/``
+
+### Formatting
+Here is example to show bracket placing and using of white spaces:
+```c
+/**
+ * Set a new text for a label. Memory will be allocated to store the text by the label.
+ * @param label pointer to a label object
+ * @param text '\0' terminated character string. NULL to refresh with the current text.
+ */
+void lv_label_set_text(lv_obj_t * label, const char * text)
+{   /* Main brackets of functions in new line*/
+
+    if(label == NULL) return; /*No bracket only if the command is inline with the if statement*/
+
+    lv_obj_inv(label);
+
+    lv_label_ext_t * ext = lv_obj_get_ext(label);
+
+    /*Comment before a section */
+    if(text == ext->txt || text == NULL) {  /*Bracket of statements start inline*/
+        lv_label_refr_text(label);
+        return;
+    }
+
+    ...
+}
+```
+
+Use 4 spaces indentation instead of tab.
+
+You can use **astyle** to format the code. Run `code-formatter.sh` from the `scrips` folder.

-If you find an issue which is very simple to fix, and you fixed it, please send a pull request against `beta` branch. 
-A simple issue could be:
-* Misspelled names
-  * Comment: misspelling or grammatical error in comments
-  * Variable: misspelled variable name (e.g. ***ojb**_next* instead of ***obj**_next*)
-  * Define: only local defines in files because global defines affect API
-  * Function: only static function name because global functions affect API
-* Not handled error case:
-  * A parameter can be NULL (during normal usage)
-  * Negative index in array or over indexing
-  * Overflow in variable
-  * Anything which is local an can be fixed with a few lines of code  
-
-### Complex issue
-If you find a complex issue which:
-* might be simple but you don't know its origin
-* affects a whole file, module or even the architecture
-* needs deeper discussion
-
-please create a **new issue** and describe
-* what you experience
-* how to reproduce the issue (maybe with example code)
-* version you are using (lvgl.h)
-* misc library version (misc.h)
-
-## How to suggest a feature?
-If you have a good and useful idea you can use GitHub issues to suggest a new feature. Please note the followings on feature requests:
-* What the new feature is about?
-* Why/Where/In which case is it useful/helpful/relevant?
-* Can you help in implementing it?
-
-After a discussion we figure out the specification of the new feature and the technical details/implementation possibilities. 
-With the knowledge of how to do it somebody can implement the new feature.
-
-Keep in mind if you wouldn't like to do the implementation there is no guarantee that it will be ready in the new future. 
-However if you would like to force it, take a look at this page: [Feature request service](http://www.gl.littlev.hu/services#feature)
-
-## How to implement a feature?
-In [docs/TODO_MINOR.md](https://github.com/littlevgl/lvgl/blob/master/docs/TODO_MINOR.md) and [docs/TODO_PATCH.md](https://github.com/littlevgl/lvgl/blob/master/docs/TODO_PATCH.md) you can see some ideas which are waiting for somebody to realize them! If want to deal with a feature from this files, please start an issue and discusse the details.
-
-The new feature should be in a new branch.
-
-## Styling guide
-
-### File format
-Use [misc/templ/templ.c](https://github.com/littlevgl/misc/blob/master/templ/templ.c) and [misc/templ/templ.h](https://github.com/littlevgl/misc/blob/master/templ/templ.h)
-
-### Abbreviations
-Please read this document to see the list of accepted abbreviations: [abbreviations-in-code](https://github.com/kisvegabor/abbreviations-in-code)
-
-### Functions
-* try to write function shorter then is 40 lines 
-* always shorter then 100 lines (except very straightforwards) 
-* in function names: 
-  * words sparated by '_'
-  * only lower case letters
-  * only clear abbreviation (OK: *lv_xy_get_title_txt*, BAD: *lv_xy_get_ttxt*)
-
-#### Global functions names (API)
-An example: *lv_btn_set_state()*
-* starts with *lv*
-* followed by module name: *btn*, *label*, *style* etc.
-* followed by the action: *set*, *get*, *refr* etc.
-* closed with subject: *name*, *size*, *state* etc. 
-  * optional like in *lv_obj_del()* it is missing
-  * could contain more words: *long_mode*, *point_all* 
-
-#### Static functions names
-Names can be used freely.
-
-### Variables
-* words sparated by '_'
-* always lower case
-* one line, one declaration (BAD: char x, y;)
-* use `<stdint.h>` (*uint8_t*, *int32_t* etc)
-* declare variables when needed (not all at function start)
-* use the smallest required scope
-* variables in a file (outside functions) are always *static*
-* do not use global variables (use functions to set/get static variables)
-
-### Defines
-* always upper case
-* starts with *LV_*
-* followed by the modul: *OBJ*, *BTN* etc.
-* closed by the subject: *ANIM_TIME*, *VALUE_MIN*, *WIDTH_DEF*
-
-### Typedefs
-- prefer `typedef struct` instead of  `struct name`
-- prefer `typedef enum` instead of  `enum name`
-- types always lowercase speperated by '_' 
-- first word for public typedefs is *lv_...*
-- next word identifies the modul: *lv_obj_...*, *lv_btn_...*
-- always add closing *..._t*
-- Examples: *lv_obj_t*, *lv_cont_layout_t*
-
-### Comments
-Before every function have a comment like this:
-
-```c
-/**
- * Return with the screen of an object
- * @param obj pointer to an object
- * @return pointer to a screen
- */
-lv_obj_t * lv_obj_get_scr(lv_obj_t * obj); 
-```
-
-Always use `/* Something */` format and NOT `//Something`
-
-Write readable code to avoid descriptive comments like: 
-`x++; /* Add 1 to x */`. 
-The code should show clearly what you are doing.
-
-You should write **why** have you done this: 
-`x++; /*Because of closing '\0' of the string */`
-
-Short "code summaries" of a few lines are accepted. E.g. `/*Calculate the new coordinates*/`
-
-In comments use `' '` when refering to a variable. E.g. `/*Update the value of 'x_act'*/`
-
-### Formatting
-Here is example to show bracket placing and using of white spaces:
-```c
-/**
- * Set a new text for a label. Memory will be allocated to store the text by the label.
- * @param label pointer to a label object
- * @param text '\0' terminated character string. NULL to refresh with the current text.
- */
-void lv_label_set_text(lv_obj_t * label, const char * text)
-{   /*Main bracket in new line*/
-    
-    if(label == NULL) return; /*No bracket only if the command is inline with the if statement*/
-    
-    lv_obj_inv(label);
-    
-    lv_label_ext_t * ext = lv_obj_get_ext(label);
-
-    /*Comment before a section */
-    if(text == ext->txt || text == NULL) {  /*Bracket start inline*/
-        lv_label_refr_text(label);
-        return;   
-    }
-    
-    .
-    .
-    .
-}
-```
-
-Use 4 spaces indentation instead of tab.

+# Roadmap
+
+This is a summary for thenew fatures of the major releases and a collection of ideas.
+
+This list indicates only the current intention and can be changed.
+
+## v8
+Planned to November/December 2020
+- Create an `lv_components` repository for compley widgets
+   - It makes the core LVGL leaner
+   - In `lv_components` we can have a lot and specific widgets
+   - Good place for contribution
+- New scrolling:
+  - See [feat/new-scroll](https://github.com/lvgl/lvgl/tree/feat/new-scroll) branch and  [#1614](https://github.com/lvgl/lvgl/issues/1614)) issue.
+  - Remove `lv_page` and support scrolling on `lv_obj`
+  - Support "elastic" scrolling when scrolled in
+  - Support scroll chaining among any objects types (not only `lv_pages`s)
+  - Remove `lv_drag`. Similar effect can be achieved by setting the position in `LV_EVENT_PRESSING`
+  - Add snapping
+  - Add snap stop to scroll max 1 snap point
+  - Already working
+- New layouts:
+  - See [#1615](https://github.com/lvgl/lvgl/issues/1615) issue
+  - [CSS Grid](https://css-tricks.com/snippets/css/a-guide-to-grid/)-like layout support
+  - [CSS Flexbox](https://css-tricks.com/snippets/css/a-guide-to-flexbox/)-like layout support
+  - Remove `lv_cont` and support layouts on `lv_obj`
+- Simplified File system interface ([feat/new_fs_api](https://github.com/lvgl/lvgl/tree/feat/new-fs-api) branch) to make porting easier
+  - Work in progress
+- Remove the align parameter from `lv_canvas_draw_text`
+- Make the copy parameter obsolate in create functions
+- Optimize and simplifie styles [#1832](https://github.com/lvgl/lvgl/issues/1832)
+- Use a more generic inheritenace [#1919](https://github.com/lvgl/lvgl/issues/1919)
+
+## v8.x
+- Add radio button widget
+- Unit testing (gtest?). See [#1658](https://github.com/lvgl/lvgl/issues/1658)
+- Benchmarking (gem5?). See [#1660](https://github.com/lvgl/lvgl/issues/1660)
+- chart: pre-delete `X` pint after the lastly set
+- chart: autoscroll to the right
+
+## v9
+- Simplify `group`s. Discussion is [here](https://forum.lvgl.io/t/lv-group-tabindex/2927/3).
+- Consider direct binary font format support
+- Optimize line and circle drawing and masking
+- Reconsider color format management for run time color format setting, and custom color format usage. (Also [RGB888](https://github.com/lvgl/lvgl/issues/1722))
+- 9-patch support for `lv_imgbtn`.
+- Handle stride. See [#1858](https://github.com/lvgl/lvgl/issues/1858)
+- Make gradients more versatile
+- Make image transformations more versatile
+- Allow snapshoting object to tranfrom them to images
+
+## Ideas
+- Use [generate-changelog](https://github.com/lob/generate-changelog) to automatically generate changelog
+- lv_mem_alloc_aligned(size, align)
+- Text node. See [#1701](https://github.com/lvgl/lvgl/issues/1701#issuecomment-699479408)
+- CPP binding. See [Forum](https://forum.lvgl.io/t/is-it-possible-to-officially-support-optional-cpp-api/2736)
+- Optimize font decompression
+- Switch to RGBA colors in styles
+- Need coverage report for tests
+- Need static analyze (via coverity.io or somehing else)
+- Support dot_begin and dot_middle long modes for labels
+- Add new label alignment modes. [#1656](https://github.com/lvgl/lvgl/issues/1656)
+- Support larger images: [#1892](https://github.com/lvgl/lvgl/issues/1892)
