[Mesa-dev] [PATCH 02/10] mesa: Enables GL_RGB and GL_RGBA unsized internal formats for OpenGL ES 3.0

[Eduardo Lima Mitev]

GL_RGB and GL_RGBA are valid internal formats on a GLES3 profile. See
"Table 1. Unsized Internal Formats" at
https://www.khronos.org/opengles/sdk/docs/man3/html/glTexImage2D.xhtml.

Fixes 2 dEQP tests:
- dEQP-GLES3.functional.state_query.internal_format.rgb_samples
- dEQP-GLES3.functional.state_query.internal_format.rgba_samples
