15 - Filling a part or the whole of a destination image with a specific color.
16 - Copying a part or the whole of a source image into a part or the whole of
17 a destination image.
18 - Copying a part or the whole of a source image into a part or the whole of
19 a destination image with a pixel format conversion.
20 - Blending a part and/or two complete source images with different pixel
21 format and copy the result into a part or the whole of a destination image
22 with a different color format. (TODO)
