Update 1003 is ready for download. Added major algorithm updates and also improved performance by over 50% baseline and with blur performance increased by like 1000x. Blur does not affect performance much after switching to the new system. Program can handle 4k textures much better. Updated tons of stuff. 

Next update 1.0.0.4 will have more algorithm changes, improved save system, added HDRIs, and better defaults to name a few things.
