2f2757fa6b ccpr: Implement stroking with fine triangle strips
Implements strokes by linearizing the curve into fine triangle strips
and interpolating a coverage ramp for edge AA. Each triangle in the
strip emits either positive or negative coverage, depending on its
winding direction. Joins and caps are drawn with the existing CCPR
shaders for triangles and conics.

Conic strokes and non-rigid-body transforms are not yet supported.

d98f78cd01 alternative no anonymous enums
Anonymous enums play havoc with documentation;
there's no name to refer to. It may be that all
enums may either be named or replaced with constexpr
without breaking anything. Try replacing all
anonymous enums in include/core to see what happens.

This names SkCanvas::SaveLayerFlagsSet but leaves
SkCanvas::SaveLayerFlags as a uint32_t, to reduce
risk as compared to review.skia.org/123584.

There's also some chance that external linkage will
break if some client refers to anonymous enum in a way
that could require its address: see
https://stackoverflow.com/questions/22867654/enum-vs-constexpr-for-actual-static-constants-inside-classes
(This CL does not require definitions + declarations)

Brought bookmaker docs in line with this change.
This also tripped over missing code in bookmaker
handling constexpr so added that as well.

1a7eb26664 resolution dependent path measure
When a dash is drawn through a canvas with a scaled up
matrix, path measure needs the pixel resolution through
the matrix to construct the dash with sufficient
resolution.

Pass the resolution through to path measure.

897c993763 Pack and align SkStrokeRec to 4-byte boundary.
The new key for the distance field path cache will contain an
SkStrokeRec. This change guarantees that we don't have any hidden
padding that has garbage values, thereby preventing apparently
equal keys from hashing to two different values. This also has
the nice effect of reducing the size of SkStrokeRec from 24 bytes
to 16 bytes.

d156d36af8 Make GrStrokeInfo inherit from SkStrokeRec
Make the code more readable by inheriting GrStrokeInfo from SkStrokeRec.
This should avoid the long .getStrokeRec() and .getStrokeRecPtr(). These
were a bit cumbersome especially in cases where an alias variable was
created for these, and then the reader had to keep track to which
StrokeInfo member the StrokeRec alias was pointing.

Removes SkStrokeRec::SkStrokeRec(const SkStrokeRec&). It was memcpying.
Try to play it safe wrt compiler using the possible padding of
superclass for subclass members. Instead, let the compiler generate
the copy constructor. Assignment operator was already
compiler-generated, so at least in that way this is consistent.

Renames GrStrokeInfo::applyDash to applyDashToPath for consistency
with superclass applyToPath.

e61c411c12 Use vertex attributes for dash effect in gpu
This will allow us to batch dashed lines together when drawing. Also, this removes the need for
a coord transform matrix in the shader, thus we save the cost of uploading a new matrix uniform
everytime we do a simple transform to the dashed line we are drawing.

5c8ee2539b Make GrContext cache the gpu paths
Creating paths for nv_path_rendering is costly. Try to reduce this
cost by caching paths based on the SkPath "hash" (i.e. SkPathRef
generation id) and stroke properties.

Adds the paths to GrContext::fTextureCache instance. Later this should
be renamed and the GrContext API should reflect the nature of the cache
better.

5f74cf8c49 Follow up on the previous patch :
- Moved the SkStrokeRec class in its own file
- Replaced SkStroke by SkStrokeRec in Ganesh
- Moved path stroking to the Ganesh level in some cases (everytime it isn't required to do it directly in SkGpuDevice). PathEffect and MaskFilter still require path stroking at the SkGpuDevice for now.
- Renamed static functions in SkPath with proper names

* No functionality shold have changed with this patch. This is a step towards enabling Ganesh Path Renderers to decide whether or not to stroke the path rather than always receiving the stroked path as an input argument.
