         X efficiency questions
         ======================

1. Is there any way to zoom XImages inside of the server?  This could
be done for example, by doing the equivalent of pixel replication from
one window by (a) copying it into a Pixmap on the server (b) Zooming a
region of this Pixmap and then (c) copying it back into a larger
window (or the original source window).  It seems like this
replication algorithm could be done by the window manager.

I can't seem to find anything which will let you do this with X11R4.
With X11R3 there was something called ZoomHints for the WM but that no
longer exists. 

2. Given the current X11R4 distribution, is there any way to do
fine-grain synchronization such that one could request the server to
do Maps and UnMaps of windows (containing for example images) so that
one could make movies?

3. Is there any way to do XGetImage/XPutImage using any sort of image
compression?

4. Is there any plans for standardizing on audio extensions for X11R5?
Are the any plans for audio compression for it if they are?

Are there any plans to do any of these things in X11R5?

		Thanks in advance,

			Pete
