From the ARB_internalformat_query2 specification:
"- VERTEX_TEXTURE: The support for using the resource as a source for
texture sampling in a vertex shader is written to <params>.
- TESS_CONTROL_TEXTURE: The support for using the resource as a source for
texture sampling in a tessellation control shader is written to <params>.
- TESS_EVALUATION_TEXTURE: The support for using the resource as a source
for texture sampling in a tessellation evaluation shader is written to
<params>.
- GEOMETRY_TEXTURE: The support for using the resource as a source for
texture sampling in a geometry shader is written to <params>.
- FRAGMENT_TEXTURE: The support for using the resource as a source for
texture sampling in a fragment shader is written to <params>.
- COMPUTE_TEXTURE: The support for using the resource as a source for
texture sampling in a compute shader is written to <params>."
For all of them,
"Possible values returned are FULL_SUPPORT, CAVEAT_SUPPORT, or NONE.
If the resource or operation is not supported, NONE is returned."
