Rev the GrContext interface. Context has draw* functions that take a new GrPaint object. Removed many of the lower-level GrGpu function call-throughs on context.

Remove unused/unsupported point size (we don't draw non-hairline points using GL points).
Change current* getter functions to get* for consistency.
Fix bounds when drawing inverse-filled paths.
