When Clutter tries to pick an ARGB visual it tried to set the GLX_TRANSPARENT_TYPE attribute of the FBConfig to GLX_TRANSPARENT_RGB. However the code to do this was broken so that it was actually trying to set the non-existant attribute number 0x8008 instead. Mesa silently ignored this so it appeared as if it was working but the Nvidia drivers do not like it. It appears that the TRANSPARENT_TYPE attribute is not neccessary for getting an ARGB visual anyway and instead it is intended to support color-key transparency. Therefore we can just remove it and get all of the FBConfigs. Then if we need an ARGB visual we can just walk the list to look for one with depth == 32. The fbconfig is now stored in a single variable instead of having a separate variable for the rgb and rgba configs because the old code only ever retrieved one of them anyway.
