From: Zack Rusin Date: Fri, 25 Oct 2013 02:05:22 +0000 (-0400) Subject: llvmpipe: support 8bit subpixel precision X-Git-Url: https://git.libre-soc.org/?p=mesa.git;a=commitdiff_plain;h=0510ec67e2c5b5ddb4755564314ccfe057555984 llvmpipe: support 8bit subpixel precision 8 bit precision is required by d3d10 but unfortunately requires 64 bit rasterizer. This commit implements 64 bit rasterization with full support for 8bit subpixel precision. It's a combination of all individual commits from the llvmpipe-rast-64 branch.
