DrawBitmap()
DrawTiledBitmap()
If the the image is bigger than the destination rectangle, it is scaled to fit.
DrawBitmap() scales the image to fit if the image has different size than
the destination rectangle.
DrawTiledBitmap() fills the destination rectangle with copies of the source
image, without changing its size.
The asynchronous versions pass the image to Application Server and return
immediately.
