Cherry pick of b561f39d01c211425bfefaaa7b31ebe097e7ba79 from AOSP master.
Due to precision loss of float math, we sometimes get 1.000001f for
dotProduct. This causes NaN result from acosf() and floor() funcs.
At the moment, this does not cause any problems on ARM, as casting
NaN to int results in 0. On mips however (possibly on x86), such cast
gives INT_MAX, so crash occurs when trying to use the resulting value.

SkiaCanvasProxy was being created with an identity transform, ignoring
any transform that may have been applied in Java (or C++) to the
android graphics Canvas it was proxy for. This CL makes sure the
DisplayListCanvas transform is propagated to the Proxy every time
asSkCanvas() is called.
We could instead move the code to the SkiaCanvasProxy constructor
if we got rid of the cached proxy on DisplayListCanvas; nobody's
using the proxy heavily enough that that should be a performance
hit at this time.

willHaveFunctor was assuming that either mStagingDisplayList
or mDisplayList would be non-null but this isn't true. Both
can be null in some scenarios (notably after a trimMemory)

Restores old SkShader matrix behavior from before the Glop refactor.
Many drawing operations draw without sending the canvas transform to
the GL shader. In such cases, we need to adapt the matrix sent to the
SkShader logic to invert the canvas transform that's built into
the mesh.

Should be explicitly passing target through, to ensure
GL_EXTERNAL_OES textures are bound correctly.

SaveLayer's performance cost is high, and proportional to the surface
being projected onto. Since ripples (even unbounded ones) are now
always projected to the arbitrary background content behind them, this
cost is especially important to avoid.
This removes the last semi-secret, saveLayer from the projected
ripple implementation.
Also fixes the HW test app to correctly demonstrate this projection
masking behavior.
Additionaly, alters PathTessellator to gracefully handle
counter-clockwise paths, and simplifies the work done by
ShadowTessellator to ensure all of its paths are counterclockwise.
