The speed might be an issue though...
The existing code for the app currently runs, using fltk-1.1.9 and
Cairo, on Linux/X-windows and win32 systems. It's coded so that the draw
method for the main scene uses either of two back-ends ("plain" fltk or
Cairo).
The Cairo implementation looks nice but is substantially slower (3~4 FPS
rather than 15~20 FPS.) Doesn't matter too much in this case, but may
matter in a Fast-Light context...
My OSX hack also runs fine, but is upside-down, and the fonts are awry.
So not actually useful, then.
I was hoping Matthias might have a view on this, as I think, from trying
to figure out the fltk-1.1 Quartz code, that some inversion of the
display Y co-ordinate is taking place to align Quartz and fltk systems,
but I don't know enough about either Quartz or Cairo...

My case is in fltk-1.1, I don't know how the fltk-2 case would compare -
porting the body of the app from fltk-1 to fltk-2 doesn't look feasible
at this stage.

This would be very useful, I think!
