for three different levels (from "Very Easy" to "Hard"). Have fun!
* Feel free to do a nicer icon!
* Stack.h is actually verbatim copy of a kernel header which we might want
to move to a more public place (like shared).
* ProgressWindow is taken from ShowImage, but adapted to suit different
needs.
* It seems to trigger a bug in the interface kit or app_server: when moving
the mouse around, the right border of a field is sometimes lost. This
does not happen in BeOS, and there is actually no code that looks responsible
for this - it might be an off by one error in the region code, though?
