From: Antia Puentes <apuen...@igalia.com>
From the ARB_internalformat_query2 specification:
"- SRGB_READ: The support for converting from sRGB colorspace on read
operations (see section 3.9.18) from 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.
- SRGB_WRITE: The support for converting to sRGB colorspace on write
operations to the resource is returned in <params>.
This indicates that writing to framebuffers with this internalformat
will encode to sRGB color spaces when FRAMEBUFFER_SRGB is enabled (see
section 4.1.8).
Possible values returned are FULL_SUPPORT, CAVEAT_SUPPORT, or NONE.
If the resource or operation is not supported, NONE is returned."
