Fix problem with `resize-minibuffer-mode'. 2008-04-26 Mike Sperber <mike@xemacs.org> * window.c (set_window_pixsize): Round up when we're shrinking, down when we're growing * to make sure that pairs of grow / shrink meant to * cancel out actually do cancel out. This fixes a problem with `resize-minibuffer-mode' where successive grow/shrink actions are meant to cancel out, but previously didn't.
