#5 merging of images

[Anonymous]

It would be nice to have functions to merge two or more
images. Concatenate them (left-to-right or
top-to-bottom), or put one image on another (using bit
operations (XOR, AND, OR or just PutPixel) including
proper alpha blending.

See imagemagick's compose for examples:
