       current_context_usage  -	Return how many	cells the current context has,
       and how many of those cells that	are currently unused.

SYNOPSIS

       current_context_usage()

DESCRIPTION
       This function sweeps the	VID  pool of the currently active context  and
       counts  O(n)  how many of these are in use and subsequently returns how
       many slots are available	in total, and how many are maked as used.  The
       number of free slots can	be found by subtracting	used from total.

EXAMPLE

	     a = fill_surface(32, 32, 0, 0, 0);
	     print(current_context_usage());
	     b = fill_surface(32, 32, 0, 0, 0);
	     print(current_context_usage());
       end
