Speaking of Ruby/DL, I have a question ...

Supposing I have a library that demands control of an event loop.  
Examples could include GLUT (glutMainLoop) or SDL, but maybe it's
something else.    What ways are there in Ruby/DL to call back into
Ruby code from the C library?

Is this even possible, or do I have to write Swig/XS for this?   Up
until this point I haven't had a need for XS/Swig, so I've typically
gone the Ruby/DL route (in what few Ruby apps I've written), or I've
used Inline::C (awesome module, BTW) in Perl.

Anyhow, ruby-sdl and ruby-opengl may exist, but occasionally I take
some pleasure in reinventing wheels...or at least in knowing how to.  
In fact, ruby-opengl might be a good example after all.    I'd really
like to stay down in C code for longer lengths of time, so this is a
case where writing one's own bindings may be useful.
