Added nan?, infinite?, degrees->radians, radians->degrees, exact-round, exact-floor, exact-ceiling, exact-truncate to racket/math
...
Altered TR's random arithmetic testing to generate single-flonums and very small flonums; fails now because of erroneous types
Fixes to sgn, sinh, cosh, and tanh:
* preserve single-flonum-ness
* correct zero sign (-0.0) for negative return values that are smaller than epsilon
* correct behavior with NaN and infinite inputs

1d, 2d and 3d function renderers no longer sample outside the function's bounds
...
This makes it more efficient to plot piecewise functions by drawing each piece with one renderer, and possible to plot functions with discontinuities by using a renderer to draw each continuous piece.

Reworked how major and minor ticks are chosen; now isosurfaces3d always shows 3-5 surfaces, and all *-ticks parameters have the same default
...
Contour and isosurface 'auto levels reorg
2D contours: z-min = z-max now makes empty plot instead of infinite loop
3D isosurfaces: d-min = d-max now makes empty plot instead of infinite loop
Fixed contracts and corner case on marching squares and cubes functions
Better selection box and point-label formatting
Increased timeout on extreme-bounds-tests.rkt
