   * Paint the frame contents.
   * SVG frames will have had matrix propagation set to false already.
   * Non-SVG frames have to do their own thing.
   * The caller will do a Save()/Restore() as necessary so feel free
   * to mess with context state.
   * The context will be configured to use the "user space" coordinate
   * system.
   * @param aDirtyRect the dirty rect *in user space pixels*
   * @param aTransformRoot the outermost frame whose transform should be taken
   *                       into account when painting an SVG glyph
