68e4e20fae Add unit test to cover incorrect image filter layer bounds bug
Pulls the matrix and layer bounds from the captured skp that was
originally clipped, and asserts that both SkMatrix and SkM44's
separate mapRect functions don't regress.

aa861a1907 Change SkMatrix::decomposeScale to use preScale
While most callers of decomposeScale only depend on the scale factors
that are returned, image filter decomposition depends on the remaining
matrix as well. Hence, the following necessary updates to work with
the new behavior of decomposeScale:

* Update imagefilter DAG sample to reflect prescaling
* Correct embedded matrix in SkApplyCTMToFilter
* Add comment to clipRectBounds() clarifying coordinate spaces and image filters

But, we want to have decomposeScale using preScale() because it then
produces a remainder matrix that can be used as the transform for the
image filter draw, instead of wrapping the image filter in an
SkMatrixImageFilter as currently done by SkApplyCTMToFilter.

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.

e72e773ad0 remove SkTCast
SkTCast is functionally equivalent to reinterpret_cast.

The comment about SkTCast helping to avoid strict alising issues is not
true.  Dereferencing a pointer cast to a pointer of an unrelated type is
always undefined, even if smuggled through a union like in SkTCast.

To really avoid aliasing issues, you need to make a union[1] of the two
value types, or better, memcpy between values.  I've had to fix
MatrixText.cpp where switching to reinterpret_cast actually let Clang
notice and warn that we're exploiting undefined behavior, and
GrSwizzle.h and SkCamera.cpp caught by GCC.

I've switched SkTLList over to use SkAlignedSTStorage, which seems
to help convince some GCC versions that fObj is used in a sound way.

[1] The union punning trick is non-standard in C++, but GCC and MSVC
both explicitly support it.  I believe Clang does not officially
explicitly support it, but probably does quietly for GCC compatibility.

This is more consistent with our other SK_BUILD_FOR_... macros,
and less likely to collide with other preprocessor logic.

(Luckily, this was defined in public.bzl, so we can do this
all in one CL in the Skia repo.)

6d6d603c81 make matrix serialization private
Moves readFromMemory, writeToMemory to private section.
No sign that these are called from google3, android,
chromium, but function names are common enough that
it's hard to know for sure.

These are used inside templates internally and for
testing, so it is not quite as simple as adding alternate
entry points in SkMatrixPriv.

20eee3f047 Added check for ill-conditioned invert
sk_inv_determinant has a guard that the determinant can't get too big so this CL only checks if the determinant gets too small.

8010632f24 remove meaningless matrix benches, add mapPts() and add new benches
mapPts definitely faster than mapPoints (identity and perspective same speed). Up to 3x for large values of N.
