void al_convert_bitmap(ALLEGRO_BITMAP *bitmap)
Converts the bitmap to the current bitmap flags and format. The bitmap will be
as if it was created anew with al_create_bitmap(3) but retain its contents.
All of this bitmap’s sub-bitmaps are also converted. If the new bitmap
type is memory, then the bitmap’s projection bitmap is reset to be
orthographic.
If this bitmap is a sub-bitmap, then it, its parent and all the
sibling sub-bitmaps are also converted.
