Details:

As the title says, the resized window isn't displayed while resizing.  A user
pretty much has to guess if they have the wanted window size, or do a trial
and error routine.

Happens with all backends, and for as long as I can remember using that
setting (at least a year now).

Let me know if more info is needed, I figured this was fairly self
explanatory.

Follow-up Comment #1, bug #24729 (project gnustep):

I'm wondering if periodically displaying the window during the resize would
work and not be too expensive.   The problem is, on slow machines this would
be a dog.

Follow-up Comment #2, bug #24729 (project gnustep):

When doing a resize while the window manager handles the windows borders we
actually try to redraw the content of the window, when the border dragging
leaves us time for that. So most likely it should also be possible, when we
handle the window border.
Somebody will need to adjust the implementation of
resizeWindowStartingWithEvent: on GSStandardWindowDecorationView to handle
periodic events and call
[window setFrame: newFrame  display: YES];
when that event gets fired. As I am never usind this setting, I hope that
somebody else will volunteer to work on that code.

Follow-up Comment #3, bug #24729 (project gnustep):

yes, live window resizing tends to be slow, especially if there is no shared
memory. All the first MacOS X versions were exceedingly slow in resizing even
on  back-then decent computers. On exported display it is of course unusable.

When GNUstep handles decoration we don't display anything, I would like at
least a border line: windowmaker lets you choose between solid window dragging
and a wireframe around (in this case we speak of dragging and not resizing and
the two should be consistent in my opinion)

Follow-up Comment #4:

current svn trunk has a change by Gregory which draws the window while
resizing, the content is updated at intervals so not to be too cpu consuming.
