      glamor_init: clamp GLSL to 120 if platform doesn't have instanced arrays · 7437b6db

      Hi,
      
      I upgraded Xwayland and the assorted libraries from git masters today,
      and noticed that glamor wouldn't work anymore on i.MX6/etnaviv. The
      error was:
      
      No provider of glVertexAttribDivisor found.  Requires one of:
          Desktop OpenGL 3.3
          OpenGL ES 3.0
          GL extension "GL_ANGLE_instanced_arrays"
          GL extension "GL_ARB_instanced_arrays"
          GL extension "GL_EXT_instanced_arrays"
          GL extension "GL_NV_instanced_arrays"
      
      The problem is that etnaviv offers GLSL 140 on GL 2.1 and glamor
      rendering assumes that glVertexAttribDivisor() is always available on
      GLSL>=130, which is not the case here. Forcing GLSL 120 makes glamor
      work fine again on this platform. After chatting with ajax in
      #xorg-devel, the following solution was proposed.
      
      This is my first time of submitting a patch, so please excuse me and
      advise if I'm doing it wrong ;)
      
      Cheers
      Lukas (mntmn)
