fillGradient coordinates

[Thomas McGrath III]

Jacques,

If you go to "Rev Online" under user mcgrath3 I have  a stack  
"Gradient lab"

Open it and select the top square with the selection tool. Open the  
Properties Inspector for that object and switch to Gradient in the pop- 
up. Now when you make changes graphically within the square you can  
hit update and see the corresponding numerical equivalents of the  
changes.

This helped me understand the From To Via aspects of Gradients.
