From 1d7048f12e7e2e8f42d27aa665f7134f8f10cf4e Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Mon, 16 Jan 2012 10:08:08 -0700 Subject: [PATCH] mesa: try RGBA_FLOAT16 before RGBA_FLOAT32 when choosing A,L,LA,I formats MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit To try to use less tex memory and maybe get better performance. Spotted by Roland Scheidegger. NOTE: This is a candidate for the 8.0 and 7.11 branches.
