Geomerative appears to apply transforms (translate/scale/rotate/skew) directly to the underlying vertex coordinates, rather than maintaining the original coords and the accumulated matrix.  So, there doesn't appear to be any (convenient) way to "reset the matrix" back to identity and put all the x/y's back where they came from originally.

Take tutorial #5 for example, where rotation is accumulated on the first letter.  Is there any way to reset that rotation?  (short of manually un-transforming in reverse after each frame, which won't really work due to accumulated errors)

Or is the expected approach to make a copy of original geometry, apply transform to the copy, use the copy as desired, then discard the copy?  (thus leaving the original untransformed)  I suppose that works, but is a bit heavy-handed.  Am I missing some "simpler" approach?

Thx,

Oh! forgot to say that making the copy is a one-liner:

Code:

RShape copy = new RShape(orignal);
 

But don't worry, I do understand that this is not optimal from a computational point of view, and that a better approach would be to keep the accumulated transformation on the shape.
