Handles 16 to 31 are defined by the FT800 for built-in font and handle 15 is
defined in the co-processor engine commands CMD_GRADIENT, CMD_BUTTON and
CMD_KEYS. Users can define new bitmaps using handles from 0 to 14. If there is
no co-processor engine command CMD_GRADIENT, CMD_BUTTON and CMD_KEYS in
the current display list, users can even define a bitmap using handle 15.
