Perspective Camera Tool
This works like the WildTools Camera tool, except that the duplicated
objects are converted from a perspective view to an orthogonal
presentation. You have the option of duplicating all objects or
selected objects.
To use the tool, draw a perspective rectangle around the objects
you wish to duplicate.
Converting perspective to orthogonal with the Camera tool
The duplicated objects will be in the correct height/width
proportion.
