If you just change rect every time you change the current
context, you should be fine? Context switching is expensive,
so assigning cached pointers from a per-context LUT to the
global variable (better than (*(current->rect))) should
be doable?

Yeah. Plus char*, plus recursion, plus getting pointers 
without making a context current... I am sure Brian has good
reasons for wanting this in GL not GLX/WGL, but I am still
not seeing why. Maybe should re-read the backlog.
