[virglrenderer-devel] [PATCH] vrend: enable multisample on GLE host with GLES >= 3.0

[Gert Wollny]

Multisample fragment operations are part of the OpenGL ES 3.0 spec and
enabling them doesnt't required the extensions to be listed explicitely.

Fixes:

 dEQP-GLES3.functional.multisample.fbo_max_samples.proportionality_alpha_to_coverage
 dEQP-GLES3.functional.multisample.fbo_max_samples.proportionality_sample_coverage
 dEQP-GLES3.functional.multisample.fbo_max_samples.proportionality_sample_coverage_inverted
 dEQP-GLES3.functional.multisample.fbo_max_samples.sample_coverage_invert

on an GLE host with GLES >= 3.0.
