As I understand it, the "default behaviour", which is currently False,
is changing to True, so toolkits written -after- R4 do not need to
worry about this as they did in R3.  Can someone please substantiate
this?  I've only heard the proposal -- not the resolution.

And of course, everyone is wondering -- what's *the* most commonly
asked question?  The noimnees are:

    - I create a window and draw into it, but nothing appears.
	(you need to map it first -- wait for Expose events)

    - I draw in a pixmap or window and it works on my monochrome
	screen, but not my color one?
	(don't use '1' and '0' in XGCValues.foreground/background)

    - I draw in a 1-bit pixmap or window and I get <various garbage/errors>
	(NOW use '1' and '0' in your GC --don't assume BlackPixel() and
	 WhitePixel() equal 1 and 0)

    - Can someone send me a postscript previewer for X?
	(probably not, but they are available via ftp and automatic
	 email servers from uunet and expo.)
