Taper transformation?

Hi everybody,

Is it possible to perform a linear taper transformation in svg
(see http://www-scf.usc.edu/~akotaobi/gptut13.html for taper 
transformation). In the transformation 3x3 matrix only six of the nine 
elements can be specified, therefore this “non affine” transformation is 
normally not possible (only scaling, translation, rotation and skewing). Is 
there a workaround? If no, would it not make sense to introduce the more 
general 3x3 matrix for transformations in a future svg version (of course 
only 8 elements are variable, the [3,3] element has to be fixed to 1)? The 
linear taper transformation would absolutely make sense for having some 
perspective effects; additionally it would also be nice to implement the 
most general case, allowing all possible linear transformations.

I hope not to bother the group with irrelevant things.

Thanks a lot
