SDL_image-1.2.11-png_channels.patch

when looking a the differences between a patch we carried in the 1.2.10 and the 1.2.11; i noted a difference in it, and after fixing that, it seemed to work.

since this is about a 256c png image it should be 1byte, not 3, thus this solves it for me.

thanks alot of the assistance. since i'm a mageia packager, i'm adding the patch to our SDL_image build.
