Finds local variable declarations that are initialized using the copy
constructor of a non-trivially-copyable type but it would suffice to
obtain a const reference.
The check is only applied if it is safe to replace the copy by a const
reference. This is the case when the variable is const qualified or when
it is only used as a const, i.e. only const methods or operators are
invoked on it, or it is used as const reference or value argument in
constructors or function calls.

After removing all unused API from SkReader32, it only had a handful
of functions, and it was (rightly) only used by SkReadBuffer. Remove
the temptation to use it by just folding it into SkReadBuffer.
SkWriter32 had some unnecessary functions as well (only used in unit
tests), so those are gone. There is still a strange relationship:
SkWriteBuffer is just an interface - SkReadBuffer is actually the
complement of SkBinaryWriteBuffer/SkWriter32. Those two classes produce
data in the exact same format, but with slightly different interfaces.
(The choice about which one is used is mostly about high-level
serialization vs. low-level helpers).

Floating-point errors in the calculations in arcTo can cause the final

a subsequent 'close' operation inserts a lineTo to close the curve. This
can result in bad miters on curves with thick outlines.
The fix is to ensure that the final point used is *exactly* the point

The fix is now staged behind a flag so that we can fix Chromium test

The change to the unit test for 389050 is interesting.
The last convexity rewrite "fixed" that case by allowing
it to be detected as convex. In the process, it actually
broke the original bug, so that rendering of the HTML
failed. This CL causes us to give up and decide that the
path is concave, but we return to rendering correctly, so
that's a win.
The bug that initiated this (950508) is effectively the
exact same bug as 2235, which is why I haven't added a new
test case. The existing test case is much more concise than
the 100K data file needed for the new one.

This separates the existing convexity logic into
two passes. The first pass detects concavity by
counting the changes in direction.
The second pass computes the cross product to
see that all angles bend in the same direction, and
computes the dot product to see if the angle
doubles back on itself.
The second pass treats axis-aligned vectors
separately, and computes the dot and cross products
by comparing point values; it does not use arithmetic
to determine convexity, so it works with all finite
values.
A compile time switch enables returning concave
for co-linear diagonal points:
If successive points are not axis-aligned, and
those points are co-linear along a diagonal;
the path is treated as concave. This is conservative
but avoids paths that change convexity when the
are translated or scaled, since transforming the
path may cause the midpoint to shift to either
side of a line formed by the endpoints.
The compile time switch is set so that co-linear
diagonal points do not affect convexity. Note that
this permits shapes formerly considered concave, such
as stroked lines with round caps, to become convex;
this accounts for many of the GM differences.
A path may double back on itself and be convex;
for instance, a path containing a single line.
Path may have multiple initial moveTo verbs, or
trailing moveTo verbs, and still evaluate as convex.
A separate entry point, SkPathPriv::IsConvex()
allows passing an array of points instead of a path.
A legacy define has been checked into Chrome to
use the old code until layout tests have been
rebaselined.
