* Introduce GrColorSpaceXform, for gamut conversion on texturesGravatar brianosman2016-07-18
| | | | | | | | | | | | | | | | | | | | | | | | | GrTextureAccess optionally includes an instance, computed from the src and dst color spaces. In all common cases (no color space for either src or dst, or same color space for both), no object is allocated. This change is orthogonal to my attempts to get color space attached to render targets - regardless of how we choose to do that, this will give us the source color space at all points where we are connecting src to dst. There are many dangling injection points where I've been inserting nullptr, but I have a record of all of them. Additionally, there are now three places (the most common simple paths for bitmap/image rendering) where things are plumbed enough that I expect to have access to the dst color space (all marked with XFORMTODO). In addition to getting the dst color space, I need to inject shader code and uniform uploading for appendTextureLookup and friends.
