note the caveat I posted about the curveTo paths being wrong. I will try and get 
a fixed Path.getBounds into the trunk code soon. I suspect that for x characters 
the errors won't be too large.

The _renderPM drawing accelerator uses T1/TTF paths internally so that's where 
the paths come from originally. I seem to remember that ttf uses quadratic 
curves so there's some messing around in there to make them equivalent to cubics 
etc etc.

The _text2Path function is actually used in the label class when stroked and 
filled labels are required; it was added 8 years ago so I've forgotten exactly 
what the requirement was there.
