Summary: KYRA1: Adjusting the intro scrolling

Initial Comment:
This is based on a discussion I had with LordHoto
yesterday.

At the beginning of the Kyra 1 intro, the screen
scrolls down to show the land. There are two slight
problems here:

* When the first explosion happens, the background for
it doesn't line up right with the rest of the
background. (This is barly noticeable, and apparently
happens in the original as well.)

* The screen scrolls one pixel at a time, and the delay
between each step is supposed to be one "tick". My
computer isn't fast enough to do this, except with the
1x scaler. As a result, ScummVM doesn't even process
repaint events, and the scroll still takes longer than
it's supposed to.

This patch attempts to fix both these problems.

Now, since I don't understand the Kyra screen page
handling, there's a certain amount of "shotgun
debugging" behind the patch. Any "Why did you...?"
question is likely to get a "Well, it seemed to work."
reply. :-)
