This patch rewrites and optimizes the Double Edge Mask node to be orders of magnitude faster. For a 1k complex mask, it is 650x faster, while for a 1k simple mask, it is only 50x faster. This improvement is attributed to the use of a new Jump Flooding algorithm as well as multi-threading, matching the GPU implementation. The result of the new implementation differs in that the boundaries of the masks are now identified as the last pixels inside the mask.
