Fixes a number of issues related to fullscreen mode. When switching out of fullscreen mode via the options dialog, setFullScreenWindow was being applied to the old reference, causing the whole screen to be blanked and unresponsive. The checkmark in the F8 menu could sometimes get out of sync with the state of the option.  Cursor wasn't always being re-scaled when scale factor was changed. It seems that setCursor can still sometimes be passed a null pointer for the hotspot, so add back in a check that was removed in r5025
