The SkM44::RectToRect function matches the semantics of
SkMatrix::RectToRect(kFill_ScaleToFit). No other ScaleToFit variants are
ported over to SkM44.
skottie uses some instances of kCenter_ScaleToFit so that functionality
may need to be added in the future (in SkM44 or in skottie). There are
no current usages of the kStart and kEnd_ScaleToFit semantics.
The SkM44::mapRect() function is implemented to correspond to the
SkMatrix::mapRect() that returns the mapped rect (instead of modifying a
pointer) and always has ApplyPerspectiveClip::kYes. This was chosen to
keep its behavior simple and because perspective clipping is almost
always the right thing to do. In the new implementation there is no
longer a performance cliff to worry about (see below). For the timebeing
mapRect is hidden behind SkMatrixPriv::MapRect().
Performance:
I added benchmarks for mapRect() on SkM44 and SkMatrix that use the same
matrices to get a fair comparison on their different specializations.
SkMatrix has a very efficient mapRect when it's scale+translate or
simpler, then another impl. for affine matrices, and then falls back to
SkPath clipping when there's perspective. On the other hand, SkM44 only
has 2 modes: affine and perspective.
On my desktop, with a Ryzen 9 3900X, here are the times for 100,000 calls
to mapRect for different types of matrices:
SkMatrix SkM44
scale+translate 0.35 ms 0.42 ms
rotate 1.70 ms 0.42 ms
perspective 63.90 ms 0.66 ms
clipped-perspective 138.0 ms 0.96 ms
To summarize, the SkM44::mapRect is almost as fast as the s+t specialization
in SkMatrix, but for all non-perspective matrices. For perspective matrices
it's only 2x slower than that specialization when no vertices are clipped,
and still almost 2x faster than the affine specialization when vertices are
clipped (and 100x faster than falling back to SkPath).
Given that, there's the open question of whether or not keeping an affine
specialization is worth it for SkM44's code size.

The reason for the assert was breaking an assert, that if the CTM was scale/translate, that after
a preTranslate, it should still be that.
This is true... unless the new translate values are non-finite. In that case, we might turn a zero
into a NaN, (0 * non_finite --> nan), so we either have to require finite args (which we don't
at the moment) or we can't make this assert. This re-land removes that assert.
This reverts commit 268ed57d71.

Devices receive the 4x4, but by default they simply downsample it to SkMatrix.
New SkM44 matrix for the impl. It differs from SkMatrix44 in a few ways
- no tracking of "type"
- faster for concat, as it does not use doubles for intermediates
- much simpler API
There are some low-bit differences in some gms, so adding a flag for clients to
stage this change. (due to faster but lower-precision in SkM44::concat)

Things to look at first are the manual changes:
- added tools/rewrite_includes.py
- removed -Idirectives from BUILD.gn
- various compile.sh simplifications
- tweak tools/embed_resources.py
- update gn/find_headers.py to write paths from the top
- update gn/gn_to_bp.py SkUserConfig.h layout
so that #include "include/config/SkUserConfig.h" always
gets the header we want.

It's been driving me nuts that I can't just write `SkMatrix44 m;`,
and I often don't care whether it's initialized or not. The default
identity constructor would be nice to use, but it's deprecated.
By tagging this constructor deprecated, we're only hurting ourselves;
our big clients disable warnings about deprecated routines and use it
freely.
A quick tally in Skia shows we mostly use the uninitialized constructor,
but sometimes the identity constructor, and there is a spread of all
three in Chromium. So I've left the two explicit calls available.
I switched a bunch of calls in Skia to use the less verbose constructor
where it was clear that it didn't matter if the matrix was initialized.
Literally zero of the kUninitialized constructor calls looked important
for performance, so the only place I've kept is its lone unit test.
A few places read clearer with an explicit "identity" to read.

which should be the bulk of cases. We'll have to manually clean up the rest

I'm not quite sure why I wrote such a convoluted API with setLoops()/getLoops().
This replaces it with a loops argument passed to onDraw().
This CL is largely mechanical translation from the old API to the new one.
MathBench used this->getLoops() outside onDraw(), which seems incorrect. I
fixed it.

Adds "grresourcecache_add" and "grresourcecache_find" bench tests to test
GrResourceCache::add and GrResourceCache::find. The tests work only
with GPU backends, since GrResourceCache needs an GrGpu.
Modifies bench tests to override SkBenchmark::isSuitableFor(Backend)
function that specifies what kind of backend the test is inteded
for. This replaces the previous "fIsRendering" flag that would
indicate test that did no rendering.
Adds SkCanvas::getGrContext() call to get the GrContext that the
canvas ends up drawing to. The member function solves a common
use-case that is also used in the benchmark added here.

Most of these issues were due to functions whose definitions appear in header files; I changed those functions to be 'static inline' instead of just 'static' or 'inline', which kills the warning for such functions.
Other functions that were static or anonymous-namespaced but were unused in cpp files were probably called at some point but are no longer; someone who knows more than I do should probably scrub all the functions I either deleted or #if 0'ed out and make sure that the right thing is happening here.
Lots of unused variables removed, and one nasty const issue handled.
There remains a single warning in thirdparty/externals/cityhash/src/city.cc on line 146 related to a signed/unsigned mismatch. I don't know if we have control over this library so I didn't fix this one, but perhaps someone could do something about that one.
