a simple way of creating projectionmappings in processing
##how it works
in the first part of the loop, you can make anything you want. The second part gets the selected area's, and maps it out onto the created vectorobjects.
##keys
a - enter edit mode
e - set current corner according to the mouse
z, s, q, d - adjust current corner pixelperfect
p - remove last area
b - toggle background
click and drag in edit mode - select new area to map
##upcomming I'm going to try to mold this into a library soon
