Using the GPU and doing filters in the compositor are two separate issues. I think after we have the software filtering done, the next step would be to implement a GL-based filter implementation library. This would initially be used for Moz2D DrawTargets which are GL-based (i.e. SkiaGL, maybe accelerated Quartz). We may wish to also use this with D2D if we want to support custom GLSL filters for canvas (although I think at the work week we decided not to? I don't remember why we decided that, and lukewarmly disagree). Then we would use this library from GL-based compositors. Or, we could do what Andreas was suggesting and have GPU-based compositors use Moz2D more directly. That's a decision to make then, when we have more information.
