Resolution:
soy.widgets.Projector is given a soy.bodies.Camera as an argument
soy.bodies.Camera has no reference to any projector which is using it
Multiple Projectors may use the same Camera
A Projector may only use one Camera at once
Projector will have .front (zNear), .back (zFar), and auto aspect ratio
Camera will have .lens (field of view angle, for "wide angle"/etc)
Reasons:
* It's far more useful to reuse a projector with a different camera
* ie, when you change scenes, etc
* widget packing will be powerful but not nessesarily fun
* It's often useful for multiple projectors to use the same camera
* case point: GNU Aetherspace's "AstroCam"-
two cameras were stuck together in the same "soya Group",
the first rendered close-up objects, the second had it's zNear setting
the same as the first's zFar and only rendered planets/etc to overcome
culling polygon counts + 16bit zbuffer inaccuracy
* Field of angle you really don't want to have different w/ multiple
projections and a soy.bodies.Camera.lens is quite intuitive
* The aspect ratio should match whatever the widget is sized to, there's very
few cases where you'd want your projection stretched/squished
* Different aspect ratios can be added later through a projector attribute
for special effects (but would still be based off Projector's size)
