[0.1.5 Preview] Using the crop

One of the more frustrating points with iRay is that it doesn't have an appropriate motion blur implementation as its implemented in terms of a single frame, and motion naturally requires keyframes (which also sucks for animations as it constantly reloads everything to update state between frames, and no accumulated lighting is stored in special acceleration structures to take advantage of temporal coherency between two frames). Some weak solutions available, but usually it requires special care. Sometimes even an RT API level support is added for it, like in Apple's Metal.

Also, I may have gone a bit overboard with Farah, over 200 renders. As we get closer to release, I'll be more and more in crunch mode, as usual. So my responsiveness will drop.
