unused headers and fixes a couple of bugs exposed by changing the random
number generator:
First, the function SkMatrix::getMaxStretch() had an error where it was testing
the square of a number against near-zero. This led to it occasionally taking a
cheaper but imprecise path for computing the eigenvalues of the matrix. It's
been replaced with a check against the square of SK_ScalarNearlyZero.
The second case was a failure in ClipStackTest, where it hit the rare case of
a practically empty clip stack (it has a single Union) and we set a tight
bounds. The bounds rect doesn't get set by GrReducedClip::ReduceClipStack() in
this case, so when it clips the reduced stack it's clipping against garbage,
and the resulting regions don't match. The solution is to initialize the
tightBounds rect.

I removed unused parameters in the tests wherever it was trivial to do so. I'm trying to get the easy ones out of the way before we get into more involved discussions around this.

identify that the AA granularity is 1/4 of a pixel, not 1/16 (along an axis).

few scanlines (of its bounds) and therefore didn't know to trim its bounds back
down. This can happen when the path's bounds are larger than the curve's bounds
(i.e. the control points are outside of the tight-bounds of the shape.)
