* suggestions:

Need a convenient way to bring up GoodNeWS after you're already running
vanilla NeWS. i.e. one .ps file you can psh in that initializes everything.
It would be nice if it didn't clobber your root menu. Instead, there could
be a GoodNeWS window on the screen that you could press the Menu button
over to get the GoodNeWS root menu.

* sys/extensions.ps:
My Sun-4/110 has a sun3 type keyboard, so it does not have a FunctionAlt
key, and I had to make the following change to sys/extensions.ps:

% NeWSMachine (sun3) eq {
% /MetaKey	keypos /LeftMeta 	get 0 get def
% } {
% /MetaKey	keypos /FunctionAlt 	get 0 get def
% } ifelse
keypos /FunctionAlt known {
  /MetaKey	keypos /FunctionAlt	get 0 get def
} {
  /MetaKey	keypos /LeftMeta	get 0 get def
} ifelse

Still doesn't work, because addkbdinterests isn't adding the meta key
suite.  I put in a horrible kludge to use the keycode for the
"Alternate" key on my keyboard (which wasn't in the keypos dict for
some reason), for the time being, instead of using the "Left" meta
key. (Since because of the way addkbdinterests does not express
interest in meta events, you don't get any keyboard events at all when
the meta key is held down)

* sys/canvas.ps

The meta key doesn't work, because of /MetaKeyEvent?, I think...

It's looking for /FunctionAlt, and should also be looking for /LeftMeta.

* newsdraw:
Seems to be in "5 setrasteropcode" mode when I try to scroll using
the scroll bars. (using copyarea?) It rather slowly reverses the colors
of the destination area it intended to scroll, instead of scrolling it
there.

XNeWS bug? Turns out copyarea with 5 rasteropcode does not move, it 
just inverts the destination area. It does correctly cause damage in 
places that became uncovered though:

framebuffer setcanvas
erasepage
600 0 translate
0 0 300 300 rectpath random random random setrgbcolor fill
0 0 300 300 ovalpath random random random setrgbcolor fill
5 setrasteropcode
% 0 setgray % this cancels the setrasteropcode
10 10 280 280 rectpath 40 40 copyarea

In looking for the triggering cause of this bug, I noticed that in
sys/menu.ps, the method /ClickMenuBar of class MenuBar leave the 
rasteropcode in state 5.

In newsdraw, assuming gsave/grestore saves and restores the rasteropcode
as part of the graphics state, it's unnecessary to save and restore it
manualy as in:
gsave currentrasteropcode ... 5 setrasteropcode ... setrasteropcode grestore

The problem seems to be in tools/newsdraw/editdraw.ps:

/DrawMarkers {	%	--
	5 setrasteropcode fill
} def

/DrawMarks { %	--
	Marked {
		newpath
		Members exch get /SetMarks ObjectSend
		DrawMarkers
	} forall
} def

I would suggest taking the 5 setrasteropcode out of DrawMarkers,
putting it at the beginning of DrawMarks, and wrapping the body of 
DrawMarks in a gsave/grestore ...

/DrawMarkers {	%	--
	fill
} def

/DrawMarks { %	--
  gsave
	5 setrasteropcode
	Marked {
		newpath
		Members exch get /SetMarks ObjectSend
		DrawMarkers
	} forall
  grestore
} def

* GoodNeWS canvases:

(at least the NeWSDraw canvas)
/EventsConsumed = /AllEvents
This should be /MatchedEvents.

The symptom is that you can't drag OpenLook windows around if you drop
them with the cursor over a GoodNeWS window. The tNt window dragging
and selection code moves the window to its final destination by
sending some sort of selection event that should drop through to the
framebuffer but doesn't, because the event gets eaten by the
/AllEvents canvas, and never makes it to the framebuffer. Some
LiteWindow clients seem to have this problem too. I think the
addkbdinterests compatibility code is fucking it up by not
redistributing the selection events that aren't ASCII...

* sys/fixes.ps:
Determination of NeWSMachine is flakey. Should not have to have PATH set up.

There should be some other way of determining the machine type.
Maybe something like "(%pipe arch) (r) file 80 string readline" as 
long as we're being system dependant...

* HyperNeWS:

Requires the file "$HOME/Stacks/.stackdirs" -- or at least I got a
dbgbreak on that when I was running the debugger. Use errored instead
of stopped?
