From: Dave Airlie Date: Wed, 14 Sep 2011 10:08:57 +0000 (+0100) Subject: mesa/colormac: introduce inline helper for 4 unclamped float to ubyte. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=81a86aea4f0990a1b8795f9e00e7a6c4ba368281;p=mesa.git mesa/colormac: introduce inline helper for 4 unclamped float to ubyte. This introduces an UNCLAMPED_FLOAT_TO_UBYTE x 4 inline function, as suggested by Brian. It uses it in a few places I noticed from previous color changes, and also some core mesa places. I haven't updated other places yet.
