General Fixes
-------------

Fixed drag and drop for modal dialogs.

- QAction
	Propagate visibility state correctly to actions added to an
	invisible actiongroup.
	
- QHttp
	Handle both upper and lower case in response headers.

- QLineEdit
	Fixed drawing problems that affected very long strings and
	the handling of trailing spaces.

- QObject
	Fixed connectNotify() and disconnectNotify() for some special
	cases.

- QPixmap
	Avoid calling detach() when setting a null mask on a pixmap.

- QString
	sprintf() again interprets strings, %s, as UTF-8 strings, not
	as Latin1 strings.

- QTabBar
	Tabbars are now correctly left aligned again.

- QTable
	Fixed shift selections after editing.
	
- QTextEdit
	Emits cursorPositionChanged() when cursor position changes
	when find() has been called.
	LogText mode: Changing fonts after appending text now
	recalculates the scrollbars properly.
	Optimized createPopupMenu().

- QVariant
	Added missing detach() calls in QVariant::as...() functions
	(e.g. asInt()).

- QWidget
	setWindowState() fixed for WindowMaximized and
	WindowFullScreen. showMaximized() and showFullScreen() now
	work for laid out widgets that have not been explicitly
	resized.
	windowOpacity() correctly initialized.

Platform-Specific Issues
------------------------

Windows:

	application executable, independently of whether it has been
	called before the QApplication constructor or afterwards.

- QSound
	Fixed isFinished() to work correctly.

- QStyle
	Fixed QWindowsXPStyle drawing flat toggle buttons.

	1.0; making widget redrawing fast again.

font database.
