Re: DirectFB: Changes to 'master'

Claudio, the Unbind semantics are a little odd.  Can you
update the
header to clairfy

1) can a window be bound to multiple windows at once?
2) if not, what error is returned
3) if you can't bind to multiple windows, why specify a
"unbind"
window in the Unbind call?

I like the idea a lot, just curious about the execution.

You can't bind (attach) the same window to multiple windows
but a window can have multiple windows bound (attached) to
it.
That is because if you bind a window to another, then the
bound window
must "follow" the window to which it's attached
when the latter moves to
a new position.
It's intutive that a window can't "follow" more
than one window.

None.
The new Bind() overrides the previous one (i.e. it
automatically
unbounds the window before binding it to the new window).

Because a window might have multiple windows bound
(attached) to it.

I realize that the documention should be detailed enough to
let people
understand these concepts immediatly, so i have just
committed a change
to the header to clarify these aspects.
