Sam Lantinga 74d83ead35 Fixed bug 2976 - Fix RGBA<->RGBA blit that was broken with the optimization from Bug 11 
id.zeta

The optimization from Bug 11 added a code branch on cases where the source RGB masks match the destination RGB masks and a optimized blit function Blit4to4MaskAlpha that always overrides the source alpha info would be chosen. Unfortunately, the branch also errorneously took over the RGBA<->RGBA blitting cases where the source alpha info should be copied, while they would instead get overriden in Blit4to4MaskAlpha.

The attached patch fixes that by handling the RGBA<->RGBA cases correctly in that branch with the original BlitNtoNCopyAlpha as well as uses an optimized Blit4to4CopyAlpha along the same vein.
