Subject: Remove the fake MSP_stereo_rendering extension
X-Git-Url: http://git.tdb.fi/?p=libs%2Fgl.git;a=commitdiff_plain;h=18f611802019c809d4257f6d1c0e341d3a645b1a

Remove the fake MSP_stereo_rendering extension

I originally created it because I thought it might be useful with VR
headsets.  Now it's apparent that VR rendering is done with different
APIs and the left/right constants are useless.  The other values of the
RWbuffer enum weren't being used for anything either.
