Description Said Abou-Hallawa 2022-05-23 09:02:02 PDT

ImageBufferAllocator is a new class which will be introduced to allow creating different ImageBuffer and PixelBuffer if the filter software appliers run in GPUProcess. The plan is to keep FilterImage allocate unaccelerated local ImageBuffer and PixelBuffer backed by Uint8ClampedArray in WebProcess. But make it allocate ImageBuffer backed by ShareableBitmap and PixelBuffer backed by SharedMemory in GPUProcess.
