* NEW: The RAISE instruction now can raise events defined in a parent class. * NEW: Timer: The Trigger method now does nothing if there is an already pending trigger. This behaviour is not backward-compatible, so it may be removed if problems arise. [COMPILER] * NEW: The RAISE instruction now can raise events defined in a parent class. [GB.DRAW] * NEW: Implement standard operators in Point and PointF classes. * NEW: Automatic conversion between Point and PointF. * NEW: 'CDraw.c' and 'CDraw.h' source files have been renamed as 'cdraw.c' and 'cdraw.h'. * NEW: Rect.Center() and RectF.Center() are two new methods that return the center of the rectangle. [GB.FORM] * NEW: FileChooser: tar archives now can be uncompressed. git-svn-id: svn://localhost/gambas/trunk@5359 867c0c6c-44f3-4631-809d-bfa615b0a4ec
