Hi Yang,
The GlyphQuads are supposed to be be internal data structures that
aren't accessed externally, so if you are needing access to them then
it suggests that public API really needs to tweaking to give you
access to what you want without grappling with the internals. Why not
have a bash at adding such an public access method and I'll review it
as poposal for an addition to the core osgText::Text implementation.
