Patch #249 - 2009/10/1 * change default for allowWindowOps resource to false. * add limit-checks for result of visual_width() function, needed from patch #242 and exposed by #244 changes (Debian #548321). * improve limit-checks in select/paste. * fix a remaining bug from patch #230 changes for displaying multi-column characters in a proportional font (report by Chris Jones). * add new resource forcePackedFont and menu entry "Packed Font" to control whether to use the font's minimum (default) or maximum width when those differ. The workaround which xterm uses to accommodate proportional fonts is not necessary with certain fonts such as unifont which happen to store a mixture of multicolumn glyphs (report by Chris Jones). * fix an (old) bug which did not restart the timer for blinking text if the only blinking text was temporarily scrolled out of view, e.g., using the scrollbar. * fix an (old) flaw in the delete-line operation where the text which is scrolled into view while the display is scrolled up was not repainted. * improve delete-line and insert-line operations, retaining selection when the selection does not intersect the deleted/inserted lines. * fix an (old) off-by-one error when an application cleared above the cursor position while the display was scrolled up, that would leave an extra line of text uncleared. * fix a similar problem where the double-size attribute would not be reset when clearing the screen while the display was scrolled up. * fix an indexing error which would occur if an application cleared a line while the display was scrolled up and was also in UTF-8 mode (Redhat #524503). The error was from patch #228 but more visible after changes from patch #244.
