bug#10920: 24.0.93; Poor response to display size changes

["Jan Djärv" <jan.h.d@swipnet.se>]

Hello.

I made a fix for bug 10962 that might have impact on this buf as well, as it incolves screen constraints.  Can you try it? It is currently in the emacs-24 branch, but I guess it will propagate to the trunk.

Thanks,

	Jan D.
