edc743a576 Add SkPathPriv::IsSimpleClosedRect
This function looks for "simple" rect paths. Simple here means begins and ends at a corner and is closed (either manually or with a close verb). Unlike SkPath::isRect this returns the starting point index (using the same start indexing scheme as SkPath::addRect).

9cb5d755e7 fix bugs in path contains
Pull out the logic to check to see if the point is on the edge
so all curve types can share.

Reorder cubic to be like conic and quad so that mixed types
consider the curves consistently.

Don't count on curve points twice if they are on the end
and compute a zero cross product.

Remove logic that checks, when there are no roots, if the
point is closer to the top or the bottom (it's always the top).

Initialize the iterator correctly when it is accessing
the list of on point curves.

Use 'multiply' instead of 'subtract' to see if the vectors
are pointing in opposite directions.

Add more test cases.

84cd621670 Implement caching of filled paths in the tessellated path renderer.
Paths are cached as tessellated triangle meshes in vertex buffers on the GPU. Stroked paths are not (yet) cached.

Paths containing no curved segments (linear paths) are reused at all scales. Paths containing curved segments are reused within a scale tolerance threshold.

In order to invalidate the cache when an SkPath is changed or deleted,
this required implementing genID change notification in SkPath. This is
modelled almost exactly on SkPixelRef::GenIDChangeListener.
However, It does not currently implement the check for unique genIDs,
so notifiers will fire when the first instance of an SkPathRef
using a given genID is destroyed.

Another caveat is that you cannot successfully add a change notifier
to an empty path, since it uses the "canonical" empty path which is
never modified or destroyed. For this reason, we prevent adding
listeners to it.

91f283bb4e change getBounds to return 0000 iff there are zero points
This is a contract change for SkPath::getBounds(), which formally was defined to return 0,0,0,0 for a 1-point path, regardless of the coordinates of that point. This seems wacky/inconsistent, and was causing other bugs (incorrect bounds) when this was unioned with other rects.

Does anyone remember why we defined it this way?

026beb52a2 SkPath::Direction serves two masters:
- input param to addFoo (e.g. addRect), where only CW or CCW are valid)
- output param from computing functions, that sometimes return kUnknown

This CL's intent is to split these into distinct enums/features:
- Direction (public) loses kUnknown, and is only used for input
- FirstDirection (private) is used for computing the first direction we see when analyzing a contour

Oddly enough this was fixed in:

https://codereview.chromium.org/16950021/ (add rect-output parameter to isRect, allowing us to return the correct bounds even if a rectagular path has a trailing moveTo)

but was reverted here:

https://skia.googlesource.com/skia/+/8fd160350ca5f57fbb1b2e03383c5778414a9b48

since it appeared to be crashing Chrome's trybots. I think it just fell through the cracks after that.

If this sticks I will land a follow on patch for the stroke issue reported in the original bug (crbug.com/247770).
