It would be very nice if the user will be able to
scroll down and up by using the mouse wheel on his/her
I don't know how hard it would be to get the scroller
controll to recognise and interpret the wheel.
Probably SDL is already equiped to recognise those
This is a very unimportant and minor feature and
should probably be implementated (if implemented at
all) only after everything else is working flawlessly.
