[PATCH] glx: Lie about GLX_Y_INVERTED_EXT

[Adam Jackson]

Well, that was lame.  The problem with reporting y inversion honestly is
that libGL asks the driver _its_ opinion of Y inversion, which it just
fabricates from whole cloth.  So then when libGL goes to compare the
driver's idea of fbconfigs with that of the server - a fairly dumb idea
to begin with - nothing matches, and direct rendering fails, and
sadness.

So until the DRI drivers are fixed we should just continue to lie about
Y inversion.  GLX_DONT_CARE is what libGL would make up for that
attribute if we hadn't sent it, so just send that instead.
