Previously, DSLVar represented local, global, and parameter variables.
This splits it into three separate subclasses.
In addition to just being a cleaner API in general, this also addresses
an issue we ran into with the upcoming DSLParser: previously, a global
DSLVar's storage was not set correctly until DeclareGlobal was called,
so an AddToSymbolTable call prior to DeclareGlobal would create the
SkSL variable with the wrong storage, causing spurious errors on
global-only modifiers. But holding off on the AddToSymbolTable tends to
break constructs like "int x = 0, y = x", so improving the API seemed
like the best way to address it.
Now that we have greater type safety around variables, we can
potentially avoid having to call AddToSymbolTable for DSLVar and
DSLGlobalVar altogether, since we know they are both supposed to end up
in the symbol table, but that isn't something I want to change in this
CL.

Add an overload to SkPathEffect that can be used when the CTM is known
at the callsite. GPU callsites are not handled here, that will be
tackled in a separate CL.
Path effects must implement the filterPath virtual that accepts the CTM,
although they are not obligated to use it. If a path effect does
use the CTM, the output geometry must be in the original coordinate
space, not device space.

of this symbol, though in C++17 we won't. Maybe we should mark this as

the 'static' will also be implicitly 'static inline' and we'll only get

If we can generalize blend[er]imagefilter, let's just move this

Reland works around Adreno issue with this formulation of sk_Clockwise:
(sk_RTFlip.y < 0.0 ? !gl_FrontFacing : gl_FrontFacing)
and instead adds this to the top of the function:
bool sk_Clockwise = gl_FrontFacing;
if (sk_RTFlip.y < 0.0) {
sk_Clockwise = !sk_Clockwise;
}
Original description:
SkSL language features that are origin sensitive now use a uniform

code.
Previously we would insert a "rt height" uniform if sk_FragCoord needed
to be flipped. sk_FragCoord,y was implemented as "realFragCoord.y" or
"rtHeight - realFragCoord.y" depending on SkSL::ProgramSettings::fFlipY.
Now we instead use a two component vector rtFlip and sk_FragCoord.y is
always "rtFlip.x + rtFlip.y*realFragCoord.y". We configure rtFlip as
either (0, 1) or (rtHeight, -1). sk_Clockwise and dFdy simiarly use
rtFlip.y to emit code that always works with either origin.

This frees the SkBlenders names for optional effects, and better

Maybe this isn't important. I see SkShaders is in core header, but
SkImageFilters is in effects, so I guess we don't have a consistent
notion for this naming yet. What I do think is semi-important is
that core headers include effects that core uses, so in this case
a Mode() factory does make sense to be in a core header, just have to
decide/bikeshed how to scope it.

calls to sample() from a function other than main.
With that tweak, we generate much better SkSL/GLSL code from every one
of our effects, avoiding the proliferation of global variables.
