A DESCRIPTION OF THE PROBLEM :
If you want to draw internationalized text along a path,
either you have to do all the layout yourself, or TextLayout
has to do it. Most people don't know enough about
internationalization and complex text to do this. Currently
TextLayout provides only horizontal layout. You can't use
LineBreakMeasurer to create multiple layouts and rotate the
graphics before drawing each layout, because
LineBreakMeasurer creates each new layout as though it was
at a line break, which is NOT what you want (it
influences bidi processing of the text).

This might be the only way to resolve the "drawString with
rotated Font transform" problem anyway. A definition of how
TextLayout hit tests and draws carets along a path, and how
it measures text, and what things like the bounds of the
layout are, would let it handle text that uses fonts with
rotated transforms. You might just treat such fonts as
defining a baseline, and multiple runs mean a curved (in the
general sense) baseline. More work for TextLayout but it
could probably optimize for the standard case.

This bug can be reproduced always.
