Hi.  By the way, can someone here tell me where in transform() is the 
code to get the screen coordinates of the transformation center?  I'm 
helping theeth with his refactor, and I've almost finished the scaling 
function (I also ported the make_trans_verts to the new code, splitting 
it up into a bunch of new functions), but I'm having a little trouble 
figuring it out.  Right now I'm using the method (but in C) that 
LetterRip posted to bf-python to find vert screen coordinates.

I figured since he used the perspective matrix I could just search for 
G->vd.persmat, or just persmat, but that didn't get me anywhere.

P.S.: By the way, since verts do not have matrices (and since I know 
next to nilch about matrices) I'm doing transformations on their direct 
loc parameters.  But it seems to me as if Objects should have this done 
too, in adition to there matrix transformation (so when you scale two 
objects, for example, the two objects get closer to each other as well 
as smaller).

Of course, this is all ultimately theeth's decision, but since I am 
helping him, it would be nice to know.
