&perspective-drawing Oh god, position becomes rotation in curvilinear. Also, implemented rudimentary curvilinear edge drawing.

&perspective-drawing Added the construction lines for subdivison because it's usually important to know where the center of the cube is.

&perspective-drawing Added a "Analysis" window that compensates for position, distance and tilt so you can analyse how each parameter effects the cube more accurately. (Sorry, it doesn't actually do the analysis for you. (Yet?))

&perspective-drawing Opted for simple, functional, auto-generated UI and added various guidelines. Think this will be all, jamming wise.

Damn, I didn't know 1 Point Perspective could do this.

Joining the Jam very late but wanted to make a little something to help me learn perspective drawing. Now I have working construction (and parallel) lines, next will be adding UI to tweak all the parameters on the fly.
