QWingedEdge should reserve the amount of segments/edges/vertices in
relative to the element count instead of length of the QPainterPath
passed in. This problem is especially severe when QTextLayout using
it to calculate the region for full line selection highlighting,
because the region used QFIXED_MAX as right most coordinate, it will
cost more than 2 GB of memory allocated just for it (recorded by
valgrind on Mac OS X), and cause crash in systems short of memory.

We need to use double precision for the angle computations, as they are
crucial to build correct winged edge structures.

do not consume excessive amounts of memory, and so can still be reasonably kept
cached with the pixmap.
Saves 8K for every pixmaps drawn to on raster paint engine. Saves about 2K for other graphicssystems.

Use a binary tree when producing the line vs line intersections to get
O(n * log n) behavior instead. Also tweak the threshold a bit to avoid
tessellating the bezier curves too finely.

The simplified test failed because the ellipse was flattened into line
segment. The other tests were due to a behavioral change in contains()
and intersect() caused by using fill based intersection in change
f7d61dab69308f0993c8a5f2232226d1713ac4a7. This needs to be reverted,
since it will return false for a rect containing a line (with no fill
area). Instead a different fix was needed in linesIntersect() to prevent
testIntersections() in tst_QPathClipper from failing.

The bezier intersections caused a lot of numerical stability issues, so
instead we now convert them to line segments. In the future it might be
possible to keep track of which bezier curve a line segment originated
from and reconstruct the bezier curves at the end.

When we compute the angle delta we can't use qFuzzyCompare as it will
cause slightly negative deltas to be snapped to 0, causing the winged
edge builder to put path edges in the wrong order.

By special-casing path vs rect intersections we can get much better
performance and more robust clipping.

Using QPainter::setClipPath results in complex (and slow) alphamasking
so this must be avoided if possible.

Using math wrapper functions instead direct call. This gives us top-level
control to what (single/double) precision we are effectively using.

Change from a relative to an absolute fuzzy compare as was the case
pre-4.4. With a relative fuzzy compare points that have an x or y
coordinate of 0 will never be merged with points that are very close to
0, for example (1e-15, 0).

The function was added in fde7f3d03782c801901f511131458d6fcb1021a5
and we believe qFuzzyIsNull is a better naming and more in line
with qFuzzyCompare.
