Said Abou-Hallawa
Because of sandboxing, accelerated image decoding is disallowed in WebContent process. Applying the gain-map in the unaccelerated code path is inherently slow. Serializing the gain-map image from WebProcess to GPUProcess and applying it to the base image there should benefit from using the accelerated backing stores.
