<krh> pq: we did have a sample feature to just set alpha to one   
      for xrgb textures
<krh> but we changed the drm buffers to set up the right  
      combination of content and format so we didn't need that
<pq> krh, yeah but I couldn't find it back then. Maybe I didn't   
     look for the right changes.
<krh> and then we discover that GLES2 doesn't let you specify  
      GL_RGB+GL_ARGB for teximage2d
<krh> eventhough that wouldn't require conversion
<krh> I suppose the thinking is that you should just do the   
      right thing in the shade
<krh> shader
<pq> krh, yes in the shader. I understood that was implemented
     once upon a time? And I have a vague recollection of seeing   
     or even touching it, but couldn't find it anymore. Maybe  
     it's just my memories of Compiz dev haunting me.
<krh> pq: no, we had that
