Delete dead code function SpotShadow::makeClockwise
Delete SpotShadow::makeClockwise, which is unused and does
not link when compiler optimizations are disabled (for debugging).
SpotShadow::makeClockwise calls non-existent function
ShadowTessellator::isClockwise, which only works because the
optimizer deletes the function.

Use path intersection instead of saveLayer+mesh to mask projected ripples
bug:14297149
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.

Re-triangulate the spot shadow.
Fix the valid umbra detection.
This looks better b/c every vertex will have one ray shooting at it, such that
we don't miss the corner.
This performs better too, due to the polygon intersection is removed and less ray
intersection. 2x performance for rect and circle for spot shadow in test app.

Improve the spot shadow computation.
Get rid of compuation of the intersection for penumbra and convex hull for umbra.
Use simple circle / normal to compute the penumbra and simple intersection for umbra.
The new way could be 2x to 4x faster from rectangle to round shape.
And this part is roughly half of the shadow computation, or 2/3 of spot shadow
computation.
This improve the spot shadow spikeness too.

Make sure the theta is correctly represented and incoming polygon is CW for shadow.
Now the theta = 0 should be on +x axis.
And cos(theta) should correctly represent x value.
Without this fix, the poly theta (from atan2) can be wrongly rotated 90 degrees.
Also, make sure the incoming polygon is CW for the shadow system.
This fix visual artifacts in recent regression for spot shadows.

Calculate and show Ambient shadow.
Basically we compute the shadow as a strip of triangles, whose alpha value
is the strength of the shadow.
We use the normal to extend the geometry.
And we use static function and try to avoid new/malloc in the computation.
