33d2055e59 GM: some header cleanup
gm.h includes sk_tool_utils.h but does not use it.

The bulk of this CL makes each gm that uses sk_tool_utils include it.

sk_tool_utils.h also provided SkRandom and SkTDArray,
so a couple GMs add those headers too.

d4631986e6 ignore max curvature at end point
When a stroked cubic folds back on itself, the
stroker draws a round join.
If the max curvature is at
the endpoint, skip the join.

dbfd7ab108 Replace a lot of 'static const' with 'constexpr' or 'const'.
'static const' means, there must be at most one of these, and initialize it at
compile time if possible or runtime if necessary.  This leads to unexpected
code execution, and TSAN* will complain about races on the guard variables.

Generally 'constexpr' or 'const' are better choices.  Neither can cause races:
they're either intialized at compile time (constexpr) or intialized each time
independently (const).

This CL prefers constexpr where possible, and uses const where not.  It even
prefers constexpr over const where they don't make a difference... I want to have
lots of examples of constexpr for people to see and mimic.

The scoped-to-class static has nothing to do with any of this, and is not changed.

* Not yet on the bots, which use an older TSAN.

4693a1748f cubic stroke fix
Normally parallel tangents means that the stroke can
be represented with a line. But looping cubics can
have parallel tangents if the loop is 180 degrees.

Check to see if the tangents direction is opposite
to subdivide further.

05424f77fa fix cubic clip in y
Follow on to https://codereview.chromium.org/1299243002/

Clip using a geometric solution if the algebraic solution
fails in Y as well as in X.

If the root finder discovers real roots that are sufficiently
far apart, the root in the range of 0..1 can contain so much
error that it is computed to be slightly smaller than 0 or
larger than 1.

In this case, binary search the mono curve for the actual
answer.

7d173403f4 subdivide path when side-clipping fails
Please review concept; I'm OK not to check this in.

If the root finder fails, subdivide the curve and try again.
This is complicated by the reversed nature of the curves;
maybe it can be simpler, but how to do that escapes me.

f9d610179d There can be only one (SkRandom)!
Remove SkLCGRandom. We already decided the new one was better, which is
why we wrote the new SkRandom.

Convert GMs that were using SkLCGRandom to use the improved SkRandom.
Motivated by the fact that these GMs draw differently on some runs. We
believe this to be a result of using the old SkLCGRandom.

Add each of the tests that were using SkLCGRandom to ignore-tests.txt,
since we expect they'll draw differently using SkRandom.

Move a trimmed down version of SkLCGRandom into SkDiscretePathEffect.
In order to preserve the old behavior, trim down SkLCGRandom to only
the methods used by SkDiscretePathEffect, and hide it in
SkDiscretePathEffect's cpp file.

992c7b03ef Add standard fonts to all GMs.
Allow GM results to be compared across machines and platforms by
standardizing the fonts used by all tests.

This adds runtime flags to DM to use either the system font context (the
default), the fonts in the resources directory ( --resourceFonts ) or a set
of canonical paths generated from the fonts ( --portableFonts ).

This CL should leave the current DM results unchanged by default.

If the portable font data or resource font is missing when DM is run, it
falls back to using the system font context.

The create_test_font tool generates the paths and metrics read by DM
with the --portableFonts flag set, and generates the font substitution
tables read by DM with the --resourceFonts flag set.

If DM is run in SkDebug mode with the --reportUsedChars flag set, it
generates the corresponding data compiled into the create_test_font tool.

All GM tests set their typeface information by calling either

  sk_tool_utils::set_portable_typeface or
  sk_tool_utils::portable_typeface .

(The former takes the paint, the latter returns a SkTypeface.) These calls
can be removed in the future when the Font Manager can be superceded.

a90c680386 Turn on quilt mode in DM.
- Rename TileGrid -> Quilt to avoid the name overload.
  - Tag all failing GMs with kSkipTiled_Flag.

You may be wondering, do any GMs pass?  Yes, some do!  And that trends towards all of them as we increase --quiltTile.

Two GMs only fail in --quilt mode in 565.  Otherwise all GMs which fail are skipped, and those which don't fail aren't. (The 8888 variants of those two GMs are skipped even though they pass.)

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.
