add support for potrace

two reasons:

1) being able to generate vector from bitmap server-side is cool
2) because the lib is GPL, you can then release the server-side source code
that act as a service so you don;t have to GPL your client-side code

Is there anyway to generate bitmap with redtamarin currently? How would you do 
something like batch resizing photos with redtamarin?

currently no it's not possible

when you are with Flash or AIR, the classes like Bitmap and BitmapData
can allow you to manipulate images at the pixel level
and this is done natively

and not present in redtamarin

to do batch resizing of photos I would go with something like ImageMagik
and control its input/output with redtamarin

I need to look at what need to be done to have native Bitmap and BitmapData 
support
but not sure yet the amount of work it needs
