I say put an appl_init() upfront and an appl_exit() before exiting

Shouldn't interfer with GDOS at all, GDOS is only needed if you use other
ouput devices than the screen itself, or want to use different fonts

Depends on your compiler since only thing you have to do is a trap
for the functions you use the only overhead
is filling some internal VDI arrays, it is not that much

VDI is not difficult to handle once you learned what the functions do
AES use windows is a lot more difficult, because you can't do it partial
