f6c85406bf use legal FirstDirection as kDontCheck sentinel
UBSAN points out that -1 isn't required to be representable
in a FirstDirection, but I think the union of all possible
fields is.

In this case, the union is 3, oring together CW (0), CCW (1)
and Unknown (2).  Since it's not one of the meaningful values
of the enum, it works as a nice sentinel.

de5d6ebb0b avoid illegal enum values in PathTest
We're testing here that when isRect() returns false,
the isClosed and direction fields are unchanged.

Instead of using illegal values (which trip up UBSAN)
test all combinations of legal values.

It looks like we were trying to use an illegal -1 bool
to do the same trick as the enum, but I think it was
legal and just always true.

f08d1d0ce1 Stop using SkTSwap.
Use std::swap instead. It does not appear that any external user
specializes SkTSwap, but some may still use it. This removes all use in
Skia so that SkTSwap can later be removed in a smaller CL. After that
the <utility> include can be removed from SkTypes.h.

dbc59ba23b path is rect track corners
This was triggered by an exploit that started the first
edge well outside the final rectangle, causing the captured
to exceed the correct result.

Ivan observes that we really only want the first and third
corners to compute the bounds, so remove the tracking code
that looks for a valid range of points, and record the
corners instead.

This is bug number ten in the series, and is the

Changing the code to track all corners is the biggest

the presence of new code may signify more bugs to come.

88ba9710b5 son of path is rect bug
This variation tricks SkPath::isRect by exploiting
that the implementation resets the point pointer to
process the close verb, and using the reset pointer
to walk over a series of points that don't move.

In addition to fixing this, rename variables to
make the line creation more obvious, since left,
right, and friends, are not the left and right.

31608c02c2 another rect is path fix
This addresses comment #17 of skbug.com/7792.

The bug overshoots the end and exploits that the
first point tracked by close isn't the first
point in the rectangle.

Fixing this slightly regresses the example
in comment #14; before it was treated as a filled
rect but now it is not; this conservative approach
doesn't cause any other regressions.

bug7792 in pathfill.cpp verifies that all paths
in the bug draw correctly by comparing CPU and GPU.

c382384848 keep SVG arcs axis aligned
Computing the arc width introduces rounding errors that cause the
arc to exceed 1/4 circle and cause integer anchored arcs to start
outside their marks. A round rect may lose convexity as a result.

Check if arcTo() inputs are integers and arc is 90 degrees;
if so, output conics which are axis-aligned on integers as well.

This is triggered when using SVG to represent a round rect.

Possible future enhancements are recorded in bug.skia.org/7383

c5e4e7437a skipRect should only work for lines (not quads or cubics)
The added unit test shows that we'll trigger SkASSERT failure if we
forgot to check that the edges are lines (instead of quads or cubics).
Similar to skia:7015, this bug is not triggered in our production
because we don't use DAA for convex paths by default. The skipRect is
an optimization just for convex paths.

a81b62674a Fix SkASSERT for convex paths with DAA
As DAA does not chop edges at Y extrema, it's valid for convex edges to
have only one edge (e.g., a single cubic edge with the valley shape \_/).

This wasn't an issue for production because DAA is never called for
convex paths by default.

a93a14a998 Convert NULL and 0 to nullptr.
This was created by looking at warnings produced by clang's
-Wzero-as-null-pointer-constant. This updates most issues in
Skia code. However, there are places where GL and Vulkan want
pointer values which are explicitly 0, external headers which
use NULL directly, and possibly more uses in un-compiled
sources (for other platforms).

c8323aa51a tiny concave path point fix
The tiny path added to PathTest.cpp has
tinier cross products (e.g. 1e-12)
so appears to be a series of unbending
lines as far as getConvexity is concerned.

This point fix looks for paths that
do not bend left or right or go backwards,
but do have a bounds, and calls them
concave.

A better fix may be to consider empty
and degenerate paths to be concave
instead of convex; I don't know if
anyone relies on the existing behavior.

Another better fix may be to change
the math to compute the path turns
even though the numbers are very small;
on the surface, very difficult.

This reverts commit dd13c02079.

Reason for revert: this breaks the Chromium DEPS roll as we break the layout_tests. I'll add a flag to guard the change in the future and enable the flag while change the layout_tests.

041da389dd Tighten SkAAClip Bounds by Path Bounds
This bug chromium:662780 exists after our original fix (https://codereview.chromium.org/2477393002/) because this path (added in unit test) is calling blitAntiRect rather than blitAntiH when the path is drifted across the boundary. (The quadratic edge drifts across the boundary after an update and sets a dX=0 line segment which triggers blitAntiRect.)

Note that I didn't assert for the dLeft = dRite = 0 case because the left/right there won't drift after the SkTMin/SkTMax in line 964/966.

Theoretically we can revert the relaxation in https://codereview.chromium.org/2477393002/ (that's only a relaxation for analytic AA, not supersampled AA). However, consider that the initial landing of analytic AA is so painful, I decide to revert that relaxation only after our successful landing...

public APIs modified by this change appear to be unused outside of Skia.

Removing these from the public API makes it easier to ensure users are
no longer using them.

This also updates GrGpu::wrapBackendXXX and the
::onWrapBackendXXX methods to clarify ownership.
