From: Gurchetan Singh <gurchetansi...@chromium.org>
The ARB_viewport_array spec says:
"Dependencies
OpenGL 1.0 is required.
OpenGL 3.2 or the EXT_geometry_shader4 or ARB_geometry_shader4 extensions
are required.
This extension is written against the OpenGL 3.2 (Compatibility)
Specification."
As such, we should ignore it for GLES2 contexts.
Fixes:
dEQP-GLES2.functional.state_query.integers.viewport_getinteger
dEQP-GLES2.functional.state_query.integers.viewport_getfloat
on llvmpipe and virgl.
