[Mesa-dev] [PATCH 3/3] mesa: Don't allow GL_TEXTURE_{LUMINANCE, INTENSITY}_* queries outside compat profile

[Ian Romanick]

From: Ian Romanick <ian.d.romanick at intel.com>

There are no queries for GL_TEXTURE_LUMINANCE_SIZE,
GL_TEXTURE_INTENSITY_SIZE, GL_TEXTURE_LUMINANCE_TYPE, or
GL_TEXTURE_INTENSITY_TYPE in any version of OpenGL ES or desktop OpenGL
core profile.

NOTE: Without changes to piglit, this regresses
required-sized-texture-formats.
