The long term idea is to eventually port some other 2D elements to this backend
(eg the HUD and 2D panels) so they use OSG (and osgText) natively, and hence
reduce the amount of C++ code we have for these jobs. (And increase our chances
of working with never OpenGL versions that forbid old style GL calls)
Long-term here means 'after 2.8 at least'.
In the meantime the more testing and feedback we can get the better. In
particular this system should offer a much more efficient way to build CDU
interfaces than many text animations, but as always it needs people to
experiment and report what features are missing to make their life easier.
Creating a 'fgcanvas' client analogous to 'fgpanel' should be doable too, since
the canvas simply renders to a single osg-Camera. Unlike fgpanel this will
require OSG instead of raw GL of course, but that's the price we pay for
unifying the rendering backend.
