 After a font is created, you can change the size by using `lv_tiny_ttf_set_size(font, line_height)`.
 
+By default, a font will use up to 4KB of cache to speed up rendering glyphs. This maximum can be changed by using `lv_tiny_ttf_create_data_ex(data, data_size, line_height, cache_size)` or `lv_tiny_ttf_create_file_ex(path, line_height, cache_size)` (when available). The cache size is indicated in bytes.
