We never set this to anything interesting, and this is really winsys state not GL state anyway. Nota bene: __DRI_ATTRIB_TRANSPARENT_INDEX_VALUE is set to GLX_NONE instead of the GLX_DONT_CARE we looked like we were doing before. This is to preserve backward compatibility with older (technically, all current) X servers, which when building their fbconfigs initialize a field named 'transparentPixel' _twice_, and the second time from __DRI_ATTRIB_TRANSPARENT_INDEX_VALUE, but then uses 'transparentPixel's value for GLX_TRANSPARENT_TYPE. Which, GLX_DONT_CARE isn't a valid value for that, so glx-fbconfig-sanity fails among much else. This is harmless, in that I don't think any DRI driver has ever wired this up (I can't find any evidence in r100 or mga history) and certainly none that we can currently load have this working.
