Additionally this CL:
forces the light colors to be opaque
forces the light direction to be normalized
adds a raster implementation
adds a gm

Visual Studio 2015 has additional warnings around noexcept and
disabling exceptions, which can be worked around with the
(undocumented) _HAS_EXCEPTIONS macro.
Visual Studio 2013 and 2015 have roundf in math.h, so use it to
avoid extra work and casts.
We avoid using cmath, as it undefs isfinite on gcc, but Visual Studio
2015 no longer provides overloads of copysign from math.h (which is
actually correct). As a result, use copysignf (which is available in
math.h in 2013 and 2015) directly.

The gm output on different font platforms is so different
that comparing images in Gold has little value. Separate the
images by appending platform information to the gm name to
group somewhat similar images together.
Note that this does not attempt to make sure that all images
generated by Gold are nearly pixel identical; it only reduces
the number of nonsensical comparisons.

(and a couple presubmit fixes)
This allows us to turn back on -Werror for LLVM coverage builds,
and more generally supports building with Clang 3.7.
No public API changes.

This adds an example of an SkShader that does normal
mapping. It has a single directional light and an
ambient light.

This should be a drop-in replacement for most for-loops to make them run in parallel:
for (int i = 0; i < N; i++) { code... }
~~~>
sk_parallel_for(N, [&](int i) { code... });
This is just syntax sugar over SkTaskGroup to make this use case really easy to write.
There's no more overhead that we weren't already forced to add using an interface like batch(),
and no extra heap allocations.
I've replaced 3 uses of SkTaskGroup with sk_parallel_for:
1) My unit tests for SkOnce.
2) Cary's path fuzzer.
3) SkMultiPictureDraw.
Performance should be the same. Please compare left and right for readability. :)

Adds a new FBO type kStencil_MSFBOType that is selected whenever
NV_framebuffer_mixed_samples extension is available. In this new
FBO type a non-msaa color buffer is created with a multisampled
stencil buffer attachment.
Replaces numSamples() with separate numColorSamples and numStencilSamples
methods in RenderTarget.
In mixed samples mode non-MSAA codepaths are used to draw simple shapes,
while NVPR-rendered paths and text are rendered with a multisampled
stencil.

A stroked conic computes the outset quad's control point by
computing the intersection of the quad's endpoints. If the
the denominator used to compute the scale factor for the
control point is small, check to see if the numerator is also
small so that the division stays bounded.
Also clean up error returns and internal function calls to
simplify the code.
Additionally, remove comic max curvature (unimplemented) and call
extrema functions instead to handle cases where the conic is degenerate
or is a line.

(This is essentially a revert of https://codereview.chromium.org/503833002/.)
This was necessary back when SkPaint was flattened even for in-process use. Now that we only flatten SkPaint for cross-process use, there's no need to serialize UniqueIDs.
Note: SkDropShadowImageFilter is being constructed with a croprect and UniqueID (of 0) in Blink. I've made the uniqueID param default to 0 temporarily, until this rolls in and Blink can be changed. (Blink can't be changed first, since unlike the other filters, there's no constructor that takes a cropRect but not a uniqueID.)

Fix path bugs exposed by the path fuzzer.
Changes to existing gm and samplecode files defer their calls to construct
SkPath objects until the first draw instead of at test initialization.
Add an experimental call to SkPath to validate the internal SkPathRef.
Fix SkPath::addPoly to set the last moveto after adding a close verb.
Fix stroke to handle failures when computing the unit normal.
Add a unit test for the unit normal failure.

The approximation uses a similar error term as the fill scan converter to determine the number of quads to use.
This also updates SampleApp QuadStroker test with conics, ovals, and stroked text.

Add RotateCircles3 back as better-named QuadStroker.
Switch pathfill test to call skia before draw instead of in
initializer to avoid triggering debugging breakpoints.

This has the side effect of requiring SkNullGLContext to use the null GL interface.
It exposes SkNullGLContext and also removes null context support from SampleApp.
