After a font is created, you can change the font size in pixels by using
:cpp:expr:`lv_tiny_ttf_set_size(font, font_size)`.
By default, a font will use up to 4KB of cache to speed up rendering
glyphs. This maximum can be changed by using
:cpp:expr:`lv_tiny_ttf_create_data_ex(data, data_size, font_size, cache_size)`
or :cpp:expr:`lv_tiny_ttf_create_file_ex(path, font_size, cache_size)` (when
available). The cache size is indicated in bytes.
By default, a font will cache data for upto 256 glyphs elements to speed up rendering.
This maximum can be changed by using
:cpp:expr:`lv_tiny_ttf_create_data_ex(data, data_size, font_size, kerning, cache_size, )`
or :cpp:expr:`lv_tiny_ttf_create_file_ex(path, font_size, kerning, cache_size)` (when
available). The cache size is indicated in number of entries. Kerning is whether to allow
