One drawback of the current implementation is that the GPU device can be unavailable at the time of the first pattern fill, which causes the GPU-accelerated canvas to be move on the main thread because of putImageData. Most of the shading patterns stuff will be moved to the GPU and in order to avoid creating some useless data we've to know if the GPU is available or not. So in this patch we create the GPU device during the worker initialization and pass a flag to the evaluator to know if the GPU is available or not.
