ImageBridgeChild::GetSingleton returns null in the GPU process. This causes DrawTargetWebgl::CopyToSwapChain to use an incorrect texture type for WebGL canvases when in the GPU process. To work around this, determine the texture type for WebGL in the content process and send it to CanvasTranslator for later usage.
