3eff3592ac need to clamp all of the cubic points after a chop, in case our finite precision
meant we didn't compute values below the chop-point.

7abfa49390 turn on pathops unit test
This temporarily disables SK_ENABLE_INST_COUNT 
( skbug.com/1219 )

This fixes a linktime error on VS2012 in
PathTest.cpp; -SK_ScalarInfinity should be
SK_ScalarNegativeInfinity instead.

This adds pathops and pathops unit tests to the
main unit tests.

Should this change destabilize anything, it should
be sufficient to comment out the pathops gypi
includes. at test.gyp:18,21.

7a90daf258 fix bug introduced with SK_IGNORE_CUBIC_STROKE_FIX where we no longer respected
subDivide limit. This caused problems with degenate paths (too much recursion).

The fix was two parts:
1. decrement the subDivide limit as we recurse
2. up the limit for cubics to 7, to match our current quality

added unittest that replicated the too-much-recursion bug.

c490f801b0 Change random number generator for 'tests' to SkMWCRandom. Also removes some
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.

64d6295b0f increase iteration count from 16 to 24, when computing cubic-line intersection.
This fixes crbug 170666. Before the fix, were were finishing the "clip" step
with a curve that was still partly negative, and so as assert would fire.

added unittest to confirm that the assert doesn't fire.

848148ec10 Fix bug in cubic-clipper (SkEdgeClipper). When we chop the cubic on Top/Bottom
of the cliprect, we (correctly) clamp the Y coordinate of the control-point
right next to the on-curve point that was chopped (this ensures we don't go
slightly outside of the clip-rect due to imperfect T value calculation). However,
the code was also clamping the other control-point as well, resulting in warping
the cubic, which could sometimes force it outside of the clip.

The fix is to just remove the line of code that clampped the 2nd control-point.

unittest added to reproduce a test cubic that triggered an assert, due to the
cubic being outside of the cliprect. The test (w/o the fix) will assert in 
a SK_DEBUG build.

consume degenerates and not, force closed and not.

4da06ab335 Modifying SkPath to store all verbs provided by the user, and to give
correct results for all stroke and fill modes even on the various types
of degenerate paths.

The goals of this patch include:
1. Have Skia store all of the verbs implied by path construction methods, even
if those define degenerate paths. The SVG implementation in WebKit, which is
backed by Skia, needs to know about all elements of the path, even degenerate
ones, for the correct drawing of markers and line caps. For example, in SVG you
should be able to draw a scatter plot by specifying a marker for vertices and
then giving a sequence of moveTo commands. Skia will not store the moveTos,
requiring a different storage mechanism.

2. Assuming 1, maintain the current Skia behavior. That is, make Skia robust to
degenerate paths.

3. Fix an existing bug in Skia where a degenerate moveTo-lineTo pair spits out
warnings from rasterization and produces incorrect results in inverse-fill
renderings.

4. Adds extensive testing for degenerate paths and path rendering in general.

To meet these goals, the patch I am proposing will result in minor additional
storage for degenerate paths (a few bytes per degenerate path, only if the user
defines such paths). There is also some additional overhead in the iteration
code, with the path now cleaned to remove degenerate segments as part of the
iteration process. I suspect this will also fix issues with computing normal
vectors to degenerate segments. Benchmarking suggests that this change may
result in slightly (< 1%) slower path drawing due to the checks for
degeneracy. This overhead could be removed (in fact, a significant speedup
could occur) if the results of iterating to clean up the path were cached.
This would cost memory, of course, and quite a bit of it.
