Summary: suggestion for "sca" command

Initial Comment:
I suggest that sca command could also take 3 arguments,
by which user could specify different scaling factors
for different axes.

Message:
Your request is now implemented as of release 7.16.4 and should be
available for testing.  Please let us know if you run into any problems
with this new feature (open a bug report if you find something wrong).  We
didn't do anything about pipes or torii, so the modeler does have to be
aware of what they're scaling.

The pipe primitive, which uses the torus, would also cause 
trouble.
When doing object edits (aka matrix edits) there are four 
options that allow you to specify which deminsion you are 
scaling -
Scale X
Scale Y
Scale Z
Scale X Y Z
That fourth option (Scale X Y Z) could be modified (I suppose) 
to allow for one global X Y and Z scaler or three distinct 
scalers for each deminsion as the user requested.

In general, I don't see a problem with doing this -- though there is at
least 
one primitive (and possibly others) that does not support such a non-rigid

transformation.  The torus, for example, presently only supports rigid 
transformations (no shearing/skewing or stretching, for example) so the 
commmand would have to take such an effect into account.  The problem 
is further complicated for any geometry that includes or uses said 
primitives.
