switch to SkPoint for the idea of drawingOrigin

Start making distinctions between three different uses
of matrices and origins.

* draw{M|O} - the information provided by the draw command.
* initial{M|O} - the drawing information captured when the
                 GrTextBlob was created.
* current{M|O} - the matrix and origin used to create the
                 data that is in the SubRun's vertices.

Where {M|O} == Matrix or Origin.

Rearrange computeTranslation and calculate_translation to
return vectors instead of taking out parameters.
Remove init() call.
