Given the increasing close date of X11R3 being let out I'm wondering
about resize hint changes.  Specfically, we have min, max, and increment
now; but that's not enough information to have a window manager report
window sizes for resize actions for many applications.  Right now, maybe
this is a widely know bug, xterm will loose its window increment
properties if the scroll bar is added.  What should happen in this case?
I think that an extra hint of min increment needs to be added.  So if you
had a text window with a vertical scrollbar with a minimum dimension of
the text region of 10x6, the hints would be as follows:
inc x	fontwidth
inc y	fontheight
min x	2 * internalborder + widthscrollbar + 10 * fontwidth
min y	2 * internalborder + 6 * fontheight
min x inc	10
min y inc	6

With this information, a window manager can report the correct number
of text lines durring a resize operation, and applications can put graphic
widgets such as scrollbars on windows without causeing problems for the
window manager.
			Or I could be completely mistaken,
