403c807971 Revert "Revert "Extend SkCanvas matrix stack to be 4x4, but with (basically) the same public API.""
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.

98bfcc7ff3 Extend SkCanvas matrix stack to be 4x4, but with (basically) the same public API.
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)

Performance: running canvas_matrix bench

3x3 version:

    167.93  	canvas_matrix_3x3	8888
    209.97  	canvas_matrix_2x3	8888
    174.87  	canvas_matrix_scale	8888
    135.30  	canvas_matrix_trans	8888

4x4 version:

    159.83 ?	canvas_matrix_scale	8888
    113.47  	canvas_matrix_trans	8888

Why faster?
- not tracking matrix_type helps a lot it seems
- faster full concat (no doubles)

c0bd9f9fe5 rewrite includes to not need so much -Ifoo
Current strategy: everything from the top

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.

4429a4f82c re-precate SkMatrix44::SkMatrix44()
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.

fab44db294 Clean up SkTypes.h.
This change removes sk_stdint.h since it is only needed for vs2008 and earlier.
This change removes SK_MMAP_SUPPORT define since it is no longer used.
This change removes the stdio.h include from SkTypes.h since on many systems
this is a very large header, few Skia files actually use it, it is
available everywhere standard, and SkDebugf should be used instead.

After this change there is no need for external users to put Skia's
include/config into their own list of includes, saving the headache
of having two header files of the same name and sometimes getting the
wrong one depending on include order.

It should be correct to simply use the bottom row of the 4x4 matrix

f02f07835e Make SkMatrix44::invert() check for finite 1/det instead of magic value
Previously we were checking to see if the magnitude of
determinant of the matrix to be inverted was less than 
1.0e-8, which is a magic number possibly plucked from 
Graphics Gems. After some discussion, it's been determined 
(ha) that we can simply check to see if 1/det is finite and 
if so proceed.

57a54e33cf Add SkMatrix44 constructor that allows user to control the initialization
method.  Preliminary results using Chromium's cc_perftests
show that we can avoid almost half of the default constructors from
redundantly/unnecessarily initializing the matrix to identity.
