corner-shape: the superellipse half-corner and Bézier handles are recomputed
for every corner

Reviewed by Simon Fraser.
Building a contour re-derives the same superellipse constants for all four
corners, two pow() calls for the half corner, plus a tanh, two exp and a
pow for the handle fit, even though they depend only on the corner-shape
parameter, which the four corners almost always share. Cache the last
result of each in thread-local storage and give the curve lists inline capacity
Peformance improvements were measured through Instruments and MotionMark
