Does anyone know whether it is possible to implement opaque window
movement under AmigaDos? What I mean by "opaque" is that instead
of just dragging the window border, you drag the entire window,
contents and all.
I was noticing the other day that 2.04 seems much smarter about
simple refresh windows. I have a fairly fast CPU in my system, and
if I try to simulate opaque movement by clicking and releasing the
mouse button quickly while moving a window, it seems to work OK,
or about as well as it does in X11. This works OK even when over a
simple refresh window. I wouldn't want to try it on a 68000, but
it seems doable on a 68040 or maybe some of the faster 68030s.
The key is that you only update it as often as you can (sort of
the equivilant concept to jump-scrolling for shell windows).
