[PATCH 4/8] glamor: Use GL_RED instead of GL_ALPHA if we have texture_swizzle

2016-01-18 Thread Dave Airlie

From: Keith Packard GL_RED is supported by core profiles while GL_ALPHA is not; use GL_RED for one channel objects (depth 1 to 8), and then swizzle them into the alpha channel when used as a mask. [airlied: updated to master, add swizzle to composited glyphs and xv paths]
