[Groff] pic: new box attribute - slanted

[Heinz-Jürgen Oertel]

Hello,
to improve a bit the look of pic generated pictures in software documentation 
I like to have an additional attribute for boxes.
With slanted boxes e 3dimensional look should be performed.
To see what I mean, please have a look at the attached PDF file.
It was generated:

box slanted -.5 color "red"
.PE
.\" /playing with gpic ---------------------- 

The current implementation is simply using an x-shift value given by the 
attribute slanted.
I'm not sure if this is the best way. Another possibility would be specifying 
a slant degree. And I need to specify maybe slantwise the y-axis.
Any suggestions to this topic?


Regards
 Heinz
