PageDrawer.drawGlyph2D() to become part of the API (make it protected instead
of private) so that I can intercept it and call something else on our special
G2D implementation.

I've recently added some new glyph APIs to a new class PDFGraphicsStreamEngine,
which PageDrawer extends. You can probably get what you need by overriding
those methods. Use of drawGlyphVector will be entirely removed from 2.0 soon.
Really though, PageDrawer isn't meant to be subclassed, ideally for 2.0 it will
be marked final and PDFGraphicsStreamEngine can be used for anyone interested
in intercepting the graphics commands (I do this myself, somewhat like your PCL
output).
