Subject: llvmpipe: Eliminate color buffer swizzling.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=75da95c50;p=mesa.git

llvmpipe: Eliminate color buffer swizzling.

Now dead code.

Also had to remove the show_tiles/show_subtiles because now the color
buffers are always stored in their native format, so there is no longer
an easy way to paint the tile sizes.

Depth-stencil buffers are still swizzled.
