I finally got a working vwarp() patch. It just adds a new function, 
vwarp(POINT, WARPS), which acts very similar to the vtransform function 
except it applies a warp to a point. This image uses a black hole warp.
However, there seems to be a memory leak somewhere...it might be in one 
of the other modifications I made, though.(Some code from a 
(non-functional) pattern blurring patch is also in there, as well as a 
vinverse_transform() patch.)
