* I want to use bitmap fonts generated with lv_font_conv.

* This layer includes a lot of code from lv_font_fmt_txt.h to define how

* @note Characters not found in the font (draw_character returns 0) will be skipped

* overlap with missing characters.
* @note The string must be null-terminated. The function will continue drawing until
* it encounters a '\0' character.
