Although I agree this at a high-level viewpoint,
there are some complication in current implementation.

- Currently SVG has fill and stroke phases for text, which HTML doesn't have.
- During painting text, it is hard to change graphics context state,
  especially we cannot push/pop the state because of SVGPaintServerGradient
  which paint the rendering result with mask on its teardown().
- Because of above reason, we need more separate (sub-)phases than HTML.
  To avoid this, code tend to hacky as the last patch...

My current plan is to add more 2 sub-phases to paint selected glyph,
in addition to Ones would be introduced at Bug 33069.
But yes, it's weired...
I think we may need more lightweight graphics context switching mechanism
for this purpose.
