2004-01-25 Fred Kiefer <FredKiefer@gmx.de>
* Source/NSAffineTransform.m: Exchanged the code of
appendTransform: and prePendTransform: to be Cocoa compatibile.
(-concatenateWith:) replaced appendTransform: with prependTransform:.
* Source/NSPrintOperation.m: (NSView
-_displayPageInRect:atPlacement:withInfo:) Item.
* Source/NSView.m (+initialize, -_rebuildCoordinates) Item.
2004-01-25 16:16 Alexander Malmberg <alexander@malmberg.org>
* Source/NSStringDrawing.m: Big redesign.
