[Dri-devel] LIBGL_DRIVERS_PATH env var

[Brian P. <br...@pr...>]

I just checked in a change for libGL: it now checks for a LIBGL_DRIVERS_PATH
env var to search for DRI 3D drivers.  The value can be a colon-separated
list of directories.  This supercedes the LIBGL_DRIVERS_DIR env var which
only accepted a single path.  The old env var is still used if the new
one is undefined.
