From bcb2f9cdb97ab2b866e238780ba68908b10e2e79 Mon Sep 17 00:00:00 2001 From: Antia Puentes Date: Sat, 19 Dec 2015 19:14:51 +0100 Subject: [PATCH] mesa/formatquery: Added SRGB_{READ,WRITE} queries 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 . 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 . 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."
