-Subject: [PATCH 5/6] glcolorconvert: implement multiple render targets for
- GLES3
-
-There are numerous slight differences required between Desktop GL and GLES3 for
-multiple render targets.
-
-1. gl_FragData doesn't exist at all and one is required to use
- 'layout (location = ?) out ...' instead.
-2. gl_FragColor doesn't exist, same as 1
-3. texture2D() has been deprecated
-
-Fortunately most of these have been taken care of with GL3 and the shader
-mangling already exists so just expand the conditions they are used in. The
-gl_FragData issue requires a new mangle pass though. We also use this new
-pass on desktop GL for consistency.
-
-Upstream-Status: Backport [1.9.1]
