Uses a single FBO and changes the attachments based on whether we need
multisample or not. This is an effort to work around presumed driver
bugs from having the same texture bound to different FBOs with different
sample counts.

doesn't reliably work on all GPUs. The tessellator needed a small fixup

The change to SkTypes.h is to remove bit-rotted code that

The GLSL spec allows matrix constructors containing vectors that would
split between multiple columns of the matrix. However, in practice, this
does not actually work well on a lot of GPUs!
- "cast not allowed", "internal error":
Tegra 3
Quadro P400
GTX 660
GTX 960
- Compiles, but generates wrong result:
RadeonR9M470X
RadeonHD7770
Since this isn't a pattern we expect to see in user code, we now report
it as an error at compile time. mat2(vec4) is treated as an exceptional
case and still allowed.

It now lives in the Compiler instead of the Inliner, and we have a
pointer to it inside the Context. I also took the opportunity to remove
a few unnecessary #includes from Context and fixed up the fallout from
this.
POTENTIALLY IMPORTANT FOOTNOTE: DSLWriter has its own Mangler object
inside of it. I experimented with removing this and having it share the
Mangler object inside the Context, but this caused failures in
"testThreading" and "testpersistentcache" CQ bots; the Expected and
Actual images would mismatch. (The Expected would be missing some
draws.) This particularly affected some blur-related tests which are
likely to be GaussianConvolution--i.e. it uses DSL.
This might be a canary in the coalmine for some quirky DSL threading
issue? e.g. using the same Context on two threads at once?

Bug 36932:
Adds a lower limit when fuzzing dash path effects, since it can produce
paths with > 140k verbs. While this is not that much memory on its own,
the triangulating path renderer can require 3+GB to complete its work
(although it doesn't actually fail).
Bug 36945, 37042:
Also has PathToTriangles check for finite paths before starting any
triangulation work. These paths were created with infinities and NaNs.
Normally such a path would be rejected at a higher level in SkCanvas.
Since the triangulator is being fuzzed directly, this emulates this.
It's included in GrTriangulator and not the fuzzer's main function
because it's a cheap test and theoretically we could encounter a path
that was built lower down (e.g. dashing or transformed to device space)
that then overflowed.
