+* 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
