			== Design Decisions ==
			* Small, algebraic objects (Point/Matrix) will be mutable, whereas large objects like a pathset will be immutable. <justification here>
			* We are using an original development method we've dubbed "Toy Driven Development". Under this process graphical toys are implemented which allow playing with the features of the library.

It is not a rendering library, instead concentrating on high level algorithms such as computing arc length.


			=== Quick Feature List ===


			(not complete)

			* C++
			* Functional programming style.
			* Points
			* Efficient affine transformations
			* Rectangles
			* Convex Hulls
			* Bounded error
			* General purpose paths:
			** Exact elliptical arcs
			** Area
			** Centroid and bending moments
			* Path Locations:
			** Determination of special spots (e.g. maximum curvature)
			** Splitting
			** Point, tangent, curvature at location
			** Efficient arc length and inverse arc length
			* Path algebra:
			** Computations such as offset curves can be written with their mathematical definition and still get a bounded error, efficient curve. (preliminary trials indicate offset done this way out performs the method used in Inkscape)
			* Arbitrary distortion (with bounded error):
			** Mesh distorts
			** Computational distorts such as the GIMP's 'vortex' plugin
			** 3d mapping (perspective, flag, sphere)
			* Exact boolean ops (elliptic arcs remain elliptic arcs)
			* Efficient 2d database
			* Implicit function plotting
			* NURBs input and output
			* Tunable path simplification
			* PDoF constraint system for CAD/CAGD
