Sculpt: brush type "Grab" with option "Frontface only" was flipping back and forth when grabbing outside of original brush area. Reason: it was calling a function that used deformed coordinates for getting normal, clipped by brush area. Now it uses original coordinates, so it always finds normal. Nicholas can determine better if tag "cache->original" should be set as default for this brush type, this far I don't dare to go :)
