From: Ian Romanick <ian.d.roman...@intel.com>
Appendix F.2 of the OpenGL ES 3.0.0 spec says:
"OpenGL ES 3.0 requires that all cube map filtering be
seamless. OpenGL ES 2.0 specified that a single cube map face be
selected and used for filtering."
Setting the field only in the context will work fine with sampler
objects (and drivers that support AMD_seamless_cubemap_per_texture)
because seamless filtering is used if *either* the context or the
sampler enable it:
"If TEXTURE_CUBE_MAP_SEAMLESS_ARB is emabled (sic) globally or the
value of the texture's TEXTURE_CUBE_MAP_SEAMLESS_ARB parameter is
TRUE, seamless cube map sampling is enabled..."
