commit-bot@chromium.org cc40f06db7 Add factory class for generating various flavors of GrTextContext.
This is the first pass of making Gr*TextContext more generic and easily
subclassed. The next stage will be making GrBitmapTextContext and
GrDistanceFieldTextContext more similar by moving the SkDraw loop into
each subclass.
