This update fixes the following issues for xfwm4:
- update to version 4.8.3
- do not exit the move/resize loop when just any key is pressed unless the operation is triggered via the keyboard
- reverting from desktop view may not focus the top most window
- recompute window's position/maximization state even if the overall size of the screen hasn't changed as the actual layout of the monitors may have changed nevertheless
- check for both forward and backward cycling modifier to be released before exiting the cycle loop
- fix a couple of memory leaks
- fix some events being lost causing the tabwin window to remain sometimes after the key has been released
- fix crash when workspace count is set to negative values
- fix crash in signal handler
- fix a bug with transients for group (including utility windows) being withdrawn as many times as parent windows where in the group, causing utility windows to disapear when switching workspaces
- do not allow applications to change the win layer on dialogs to prevent dialogs to be unreachable in some Java based applications
- do not enforce the size increment only if the size request comes from the application itself
- dropped obsolete xfwm4-4.8.2-careful-layer-manipulation.patch, xfwm4-4.8.2-fix-disappearing-transient-windows.patch, and xfwm4-4.8.2-fix-resizing.patch
- 761550: added xfwm4-fix-sticky-parentless-dialogs.patch (bxo#8263)
