From 531309a5f05a2b56cb9c30b1fbdd85233c275169 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Thu, 24 Sep 2015 09:36:44 -0600 Subject: [PATCH] st/mesa: try PIPE_BIND_RENDER_TARGET when choosing float texture formats MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit For 8-bit RGB(A) texture formats we set the PIPE_BIND_RENDER_TARGET flag to try to get a hardware format which also supports rendering (for FBO textures). Do the same thing for floating point formats. This allows the Redway3D Flat demo to run.
