Currently, the tile offset is added when drawing the picture. This might
have made a tiny bit of sense when the picture was always positioned at
origin, but with a picture cull rect offset things looks really strange.
For example, to specify a tile == the picture cull rect we have to pass
in [-cullrect.x, -cullrect.y, cullrect.width, cullrect.height]. Yikes.
(there's also a bug when not passing a tile, as we use a default tile
== cullrect but don't compensate for the above oddity)
This changes the semantics of the tile offset: it is now subtracted when
drawing the picture tile. As a consequence, one can pass in a tile equal
to the cull rect and get the expected behavior (same when not passing
a tile).
This will require a minor Blink change with the roll, as one client
works around the current behavior:

SkNVRefCnt is a variant of SkRefCnt that's Not Virtual, so weighs 4 bytes
instead of 8 or 16. There's only benefit to doing this if the deriving class
does not otherwise need a vtable, e.g. SkPicture.
I've stripped out some cruft from SkPicture, rearranged fields to pack tightly,
and added compile asserts for the sizes of SkPicture, SkRecord, and
SkVarAlloc.

This CL:
1) removes the EXPERIMENTAL_optimize on SkCanvas & SkDevice
2) moves the saveLayer gathering step to endRecording
3) Replaces GPUOptimize with SkRecordComputeLayers
4) Update bench_pictures & render_pictures to provide the new flag
#2 also necessitated moving the BBH computation (and record optimization) out of SkPicture's ctor (and into endRecording)

In cull_line we must also check if both points are the same. Otherwise we
fail the assert in the else "SkASSERT(dy && !dx)".

This change is here since previously color bitmap text was rendered using a
geometry processor in the coverage stage. The problem with this is that we
cannot correctly do xfer modes with this method. So I now make color bitmap text
draw using a color stage in the same was as a draw bitmap call.
One issue that arrises from this fix is that we end up adding this final color
processor after any previous color processors. Thus if we have a custom blend
implemented as a color processor it will be before this text one and we won't
blend correctly. This issue will get fixed once an xfer processor is fully
implemented. I have hacked a test locally to show that if we can add the text
color processor to the begining of the color stages we do blend correctly in all
cases (so the xfer processor will be a fix).

The imagemagnifier GM was applying the filter both to a saveLayer()
restore() around the whole scene, as well as to each individual
text draw.
Applying the filter only in the saveLayer() makes it run ~20x faster
on my Linux box, and the quality is improved as well (since the
primitives are not double-filtered).

This is basically how blink uses the filter. Currently, I can't use it for "ShadowOnly" mode with the filter at all, but instead of copying the code and risking to have the codepaths diverge, I'm simply going to add the option here.

Draw thick-stroked Beziers by computing the outset quadratic, measuring the error, and subdividing until the error is within a predetermined limit.
To try this CL out, change src/core/SkStroke.h:18 to
#define QUAD_STROKE_APPROXIMATION 1
or from the command line: CPPFLAGS="-D QUAD_STROKE_APPROXIMATION=1" ./gyp_skia
Here's what's in this CL:
bench/BezierBench.cpp : a microbench for examining where the time is going
gm/beziers.cpp : random Beziers with various thicknesses
gm/smallarc.cpp : a distillation of bug skia:2769
samplecode/SampleRotateCircles.cpp : controls added for error, limit, width
src/core/SkStroke.cpp : the new stroke implementation (disabled)
tests/StrokerTest.cpp : a stroke torture test that checks normal and extreme values
The new stroke algorithm has a tweakable parameter:
stroker.setError(1); (SkStrokeRec.cpp:112)
The stroke error is the allowable gap between the midpoint of the stroke quadratic and the center Bezier. As the projection from the quadratic approaches the endpoints, the error is decreased proportionally so that it is always inside the quadratic curve.
An overview of how this works:
- For a given T range of a Bezier, compute the perpendiculars and find the points outset and inset for some radius.
- Construct tangents for the quadratic stroke.
- If the tangent don't intersect between them (may happen with cubics), subdivide.
- If the quadratic stroke end points are close (again, may happen with cubics), draw a line between them.
- Compute the quadratic formed by the intersecting tangents.
- If the midpoint of the quadratic is close to the midpoint of the Bezier perpendicular, return the quadratic.
- If the end of the stroke at the Bezier midpoint doesn't intersect the quad's bounds, subdivide.
- Find where the Bezier midpoint ray intersects the quadratic.
- If the intersection is too close to the quad's endpoints, subdivide.
- If the error is large proportional to the intersection's distance to the quad's endpoints, subdivide.

As written, all the layers in the MPD Sierpinski GM are full screen. This CL bounds each layer to reduce overdraw.
This CL will cause differences in:
multipicturedraw_sierpinski_simple
multipicturedraw_sierpinski_tiled

This adds a "biglayer" variant that creates a picture with a single big layer. The tiling composition will test whether the layer hoisting code correctly caches the layers with their clipping information.

Feature-wise, this removes:
1) BBH support;
2) peephole optimizations;
3) record-time text op specializations;
4) the guarantee that SkPaints are flattened.
This deletes the optimizations GM, which only exists to test the peepholes of
the old backend. SkRecord optimizations are unit tested, and if that ever fails we
can think about adding another GM like this, but they're different enough we'd
want to start from scratch anyway.
We need to keep the code that plays back the specialized text ops around for
a while for compatibility with existing .SKPs that have those ops recorded.

Having the picture contents not actually reside in the 0,0..W,H range wrecks havoc with the layer hoisting. The hoisting works correctly but since the picture don't fulfill their contract the results look incorrect.
This CL just translates the picture's contents to the right so they are within the picture bound.
