Subject: [PATCH] Add missing guard required for GLES to disable stereo
rendering
fmt.stereo()/StereoRender will evaluate to false for GLES, guard the whole
block so GL_*_RIGHT is not used.
Change the GL_*_LEFT defines for GLES so it actually refers to a front/
back buffer, otherwise on GLES the invalid constant 0 will be used to
select the front (0x404) and back buffer (0x405). Remove GL_*_RIGHT
defines to avoid any accidental, unguarded use.
