[Mesa-dev] [PATCH 2/5] mesa: Fix error returned by glCopyTexImage2D() upon an invalid internal format

[Eduardo Lima Mitev]

Section '8.6 Alternate Texture Image Specification Commands', page 161 of the
OpenGL ES 3.1 spec, and page 207 of the same section in the OpenGL 4.5 spec
state in relation to CopyTexImage2D method:

    "An INVALID_ENUM error is generated if an invalid value is specified for
     internalformat."

Fixes 1 dEQP test:
* dEQP-GLES3.functional.negative_api.texture.copyteximage2d_invalid_format
