I agree with reusing mwm hints, icccm hints where they do the job.

Well, if I switched to E in it's current state, I would spent a lot of
hacking themes trying to make it work in a sane manner (fvwm* have the
same problem). Instead I wrote a window manager that works well by
without any configuration for anyone that can be productive with windows
or os/2 interface. This means mostly having a usable FEEL, because feel
*much* more important than look. Icewm provides configurable look, but
feel is mostly hardcoded to make things consistent and productive.

I strongly disagree. We need standard default sizes in addition to 
any dynamic rendering. See below for some reasons.

More than icon size is needed in a wm.

I agree with this. I would like to see something like this:

WIN_ICON_SIZES array of (w,h) set on the root window.

applications sets 

WIN_ICONS array of pixmap,mask handles on it's own window.

However we NEED a set of standard sizes for several reasons:
  - rendering an icon to any requested size will probably produce uglier
    than making icon for individial size manually.
  - applications might not be able to render icons, for example if they
    written in script languages.
  - rendering on the fly is possibly expensive and a waste of time

Of course having this capability would be nice (can truetype handle

Assuming you use imlib.

Well each applications should provide icons in both 24 and 8 bit depths
in several standard sizes:

  16x16 x8 x24
  32x32 x8 x24
  48x48 x8 x24

I think we should also specify the default naming convention for icons
Icewm currently uses:
  icon_16x16.xpm and
but it does not currently handle 24bit icons. One problem is that
XPM is not very good for true color files (they are large) so using
something like ppm (binary) would be better.

Yes. However this property is not quite adequate, because it can not 
adequately specify multiple desired icons sizes. It can only specify 
min,max size and step between them.

I understood that app should generally draw an icon using graphics
commands, not scaling. Scaling icons does not produce acceptable 
results (ugly icons).

Well, I can implement my own proposals tomorrow and have them work,
but it is wiser to agree on a design first.

I agree, most X programs have butt-ugly icons of random sizes, 
which makes them mostly useless.

This is cool. It is probably good not to use corba for performance
anyway, (sound must be realtime).
