Now we also consider the texture base format for color textures too. The basic idea is if we're sampling from a RGB texture we always want to get A=1, even if the actual hardware format might be RGBA. We had assumed that the texture's A values were always one since that's what Mesa's texstore code does. But if we render to the RGBA texture, the A values might not be 1. Subsequent sampling didn't return the right values. Now we examine the user-specified texture base format vs. the actual gallium format to determine the right swizzle. Fixes several fbo-blending-formats, fbo-clear-formats and fbo-tex-rgbx failures with VMware/svga driver (and possibly other drivers). No other piglit regressions with softpipe or VMware/svga.
