From the ARB_internalformat_query2 specification:
"- SRGB_DECODE_ARB: The support for toggling whether sRGB decode happens at
sampling time (see EXT/ARB_texture_sRGB_decode) for the resource is
returned in <params>.
Possible values returned are FULL_SUPPORT, CAVEAT_SUPPORT, or NONE.
If the resource or operation is not supported, NONE is returned."
