* blend_pixels patched 8-24-05 to fix bug #163721. Note that this change
* causes the function to treat src1 and src2 asymmetrically. This gives the
* right behavior for the smudge tool, which is the only user of this function
* at the time of patching. If you want to use the function for something
* else, caveat emptor.
