[VirtualGL-Devel] [PATCH] Make glXGetConfig/glXGetFBConfigAttrib return errors instead of dying

[Nathan K. <nat...@sp...>]

Rather than ripping out the rug from under the user, worst-case the app 
doesn't draw correctly but at least the user has a chance to save.  The 
trace logs will still give necessary info to know something went wrong.

This is the logical follow-up to the previous patch.  Given enough time,
I suggest an app that triggers one of these cases will be encountered.
While we don't want to start baby-sitting bad applications, we should at 
least be as lenient as other known GL drivers.
