Thanks for working on this.  The results in p.b-t.b look great!  Your
contribution is appreciated and I will work to incorporate this fix into POV
3.5.

I have two comments and questions:
You completely rewrote MTransUVPoint.  Really, what you've created is a new
function, not a new version of MTransUVPoint.  Your function takes
completely different inputs and yeilds a different output.  This new
function deserves a new name.  Do you have a suggestion?

Also, since MSquareQuad does not need to be called, we'll probably remove
the call, but leave the function.  It is part of the general collection of
matrix functions, so it will probably stay in case sombody needs to use it
in the future.  Also, if Shape->Mapping is no longer used, we should remove
it completely.  I'm not sure if it is used anywhere else - do you know?

One more question:  Do you have a simple test scene that I could use for
testing?  (Maybe with two patches with a pattern-based texture.)  Thanks!!!

-Nathan
