0013 It can perform the following operations.
0014
0015 - Filling a part or the whole of a destination image with a specific color.
0016 - Copying a part or the whole of a source image into a part or the whole of
0017 a destination image.
0018 - Copying a part or the whole of a source image into a part or the whole of
0019 a destination image with a pixel format conversion.
0020 - Blending a part and/or two complete source images with different pixel
0021 format and copy the result into a part or the whole of a destination image
0022 with a different color format. (TODO)
