Use vga_getkey() to read the keyboard, if you see an ESC read it again
immediately (without waiting). If you get 0 then no other key was
pressed and you have an ESC key press, if you get anything else then
treat it as an escape sequence.
I forget if you need to explicitly tell SVGALIB to use vga_getkey() as
non-blocking. If it does, then you'll need to set it to non-blocking.
I don't know about this ncurses problem, but this method also works with
normal terminals connected to a unix box, you just need to be sure to
set the line disaplin for the terminal to non-blocking, set stdin to
unbuffered using setbuf or setvbuf and away you go.
