It is written in the basic documentation of the vImage framework that it was precisely done to support real-time or near real-time geometrical operations on raster files like rotation and interpolation. I must admit, however, that I never dug into it myself: I do a lot of CALayer affine transforms in the application I'm writing, but I don't care about rotated pixels since I mostly deal with vector data.
