Subject: llvmpipe: fix swizzling of texture border color
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3446af01798bd4bfcdb68f984a3ecd8f7ff9a4a4;p=mesa.git

llvmpipe: fix swizzling of texture border color

The pipe_sampler_view's swizzle terms also apply to the texture border
color.  Simply move the apply_sampler_swizzle() call after we fetch
the border color.

Fixes many piglit texwrap failures.
