Summary: new theme: changing overlay size

Initial Comment:
When starting COMI from the standard 640x400 launcher,
the overlayheight changes from 400 to 480. A
corresponding SCREEN_CHANGED event is sent for this to
the scumm engine.

However, the _screen surface in ThemeNew is still at
the 640x400 size at this point. The newgui event
handler does check for SCREEN_CHANGED events (and
recreates the _screen surface if it gets one), but that
event handler isn't active for this particular screen
change.

This causes a segfault as soon as F5 is pressed, since
it tries to copy a 640x480 overlay into a 640x400 surface.
