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.
