Assistant glitch workaround demo image

I've found a workaround for this, at least in regard to 5 point perspective
using fisheye assistants.

Attached is a blank image demonstrating this workaround. With it you can zoom
in to your heart's content without the canvas blacking out (and it's surprising
just how happy that makes me:)).

The key to avoiding the issue is that the area defined by either fisheye must
be completely outside of the image. Since fisheyes repeat themselves once on
either side (along their defining line segment, a feature usually used for
making panoramas) you will still get assisted drawing on the image if things
are set up properly. Note: If you want to change the resolution of this demo
image adjust pixels per inch or pixels per cenimeter. Assistants use points for
their positional unit, and points key off of inches or centimeters, so if you
scale the image any other way, the assistants will not match that scaling.
