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.
