al_draw_bitmap - Allegro 5 API
void al_draw_bitmap(ALLEGRO_BITMAP *bitmap, float dx, float dy, int flags)
Draws an unscaled, unrotated bitmap at the given position to the
current target bitmap (see al_set_target_bitmap(3)).
flags can be a combination of:
o ALLEGRO_FLIP_HORIZONTAL - flip the bitmap about the y-axis
o ALLEGRO_FLIP_VERTICAL - flip the bitmap about the x-axis
Note: The current target bitmap must be a different bitmap. Drawing
a bitmap to itself (or to a sub-bitmap of itself) or drawing a
sub-bitmap to its parent (or another sub-bitmap of its parent) are
not currently supported. To copy part of a bitmap into the same
bitmap simply use a temporary bitmap instead.
Note: The backbuffer (or a sub-bitmap thereof) can not be
transformed, blended or tinted. If you need to draw the backbuffer
draw it to a temporary bitmap first with no active transformation
(except translation). Blending and tinting settings/parameters will
be ignored. This does not apply when drawing into a memory bitmap.
