[Bf-modeling] Improving the mirror modifier

[Noel Stoutenburg]

Friends,

. Where I wrote about scaling the z axis to -1, I should have made it 
clear that this was in addition to the -1 scaling that already existed 
on the x and y axes in the test object that Daniel linked to. Using the 
technique Daniel thoughfully provided, scaling using a scale factor of 
-1 on a single axis provides symmetry projection through a plane 
(basically the same functionality as the current mirror modifier); 
scaling using a scale factor of -1 on two axes provides symmetry 
projection through a line, and scaling using a scale factor of -1 on all 
three provides symmetry projecton through a point.
