All `draw_*` callbacks receive a pointer to the current `draw_ctx` as their first parameter.  Among the other parameters there is a descriptor too that tells what to draw.
E.g. for `draw_rect` it's called [lv_draw_rect_dsc_t](https://github.com/lvgl/lvgl/blob/master/src/draw/lv_draw_rect.h),

for `lv_draw_line` it's called [lv_draw_line_dsc_t](https://github.com/lvgl/lvgl/blob/master/src/draw/lv_draw_line.h), etc.
