Summary: Transition effect glitch (regression?)

Initial Comment:
I've been playing through Day of the Tentacle with a
recent CVS snapshot.

I noticed a slight glitch that I believe may be a
regression. In the future, after showing one of those
"Meanwhile..." interludes, the screen wasn't completely
cleared. Presumably because virtscreen 0 covered the
entire screen during the interlude, but not afterwards.

That meant that for a brief time the verb/inventory
area of the screen contained garbage.

I'm attacing a saved game. It should be enough to
simply walk into the kitchen or entrance hall (but not
through the chimney or into the kennel?) to trigger the
interlude.

I'm not sure how to fix it, but I did notice that
initVirtScreen() will call setDirtyRange() in most
cases. If I add a call to updateDirtyScreen() as well,
the glitch goes away.
