In most places we were using 0.25 (maximum distance between the actual
and approximated curves). In these few places, we were using 0.5, which
is enough to produce visible errors.
Added a GM that demonstrated the problem as reported - many of the arcs
with radius ~8 were previously closer to round-rects than circles.

GrRenderTargetOpList maintains an array of op chains. When it receives a
new op it tries to add it to an existing chain, working backwards from
the end of the current array. If the op can be added to a chain it
additionally tries to merge the new op with ops already in the chain
before adding it to the tail of the chain.
In forward combining it tries to concatenate chains. If chains can
concatenate it also attempts to merge ops between the two chains.
Now op chaining results reported by Op subclasses must be transitive.
Moreover, if op A is able to merge with B then it must be the case that
any op that can chain with A will either merge or chain with any op that
can chain to B.

Adds setVertexAttributes and setInstanceAttributes. These take a pointer
to the first attribute, and a count. The count is the total number of
possible attributes, though some may not be initialized. The base class
computes the number of initialized attributes, pre-computes the strides,
and only allows subsequent access to the initialized attributes.
The attributes need to be allocated contiguously. Some GPs place them in
an array, though most just place them as consecutive members, and pass
a pointer to the first one.
Indexed access would be possible, but now it makes more sense to iterate
over all attributes, so enable that, and use range-based for everywhere.
Completely remove the per-attribute offset helper (again - possible, but
not real helpful), and make the stride always available. In many ops,
just use the GP's computed stride, rather than re-computing it.

edging settings are needed for metrics calls, as well as drawing, hence
we really have to include them in almost every SkFont call/usage, so I
guess we can just accept them as real.
This seems to imply that we have to document what happens in drawTextBlob,
since it has a bunch of SkFonts (runs) AND a paint. This is the situation
today of course, and I had hoped to simplify it, but I think I've failed.
Proposal dox for drawTextBlob.
drawTextBlob respects the paint when drawing the blog, but it IGNORES the
paint's antialias (and lcdrender) flags, as these are already specified in
the blob's runs.
