Blit a 24-bit surface to a 32-bit target surface using SDL_UpperBlit

When blitting a 24-bit source surface with default format (GBR888 on test system) to a 32-bit target surface (with not per-pixel alpha in the test case) the Red and Blue components of the source pixels are swapped when copied to the target surface. See the attached example program.

This is fixed in 2.0.4 RC2, thanks for the great test program!
