Description
This is the new code we discussed on bug #937017 (SAM: Inventory masking regression). That bug is fixed by this code. Also, bug #777999 (COMI: Text on scrolling backgrounds) is fixed. Contrary to my hopes, bug #744650 (SAM: screen scrolling doesn't redisplay subtitles) is not fixed, though. It seems to be caused by something else; I noticed that the camera won't move until the text ends (so you can delay the camer movement infinitely by repeatedly 'e'xamining an object)...
What it does is this: a new surface is added into which text is rendered (not all text: only text on double buffered virtual screens; and only text for which the ignoreCharsetMask flag isn't set). This text is then composited over the actual graphis by Gdi:: drawStripToScreen.
The result is that it is possible to keep the text fixed while the game graphics behind it scroll (relevant for the above mentioned COMI bug). Also, the mask level 0 isn't (ab)used for the charset mask anymore, which fixes the SAM regression.

have to take back that last bit :-). It turned out the change worked on base CVS, too. Well, the much the better.

This patch really simplifies all the code surrounding charset masking, and it seems to fix the issues that it should.
Big OK from me. :)

OK, so I just checked it in. We'll see how it develops from here, I guess :-)

Small update for the patch: I discovered another benefit of it, you can skip the code in restoreVerbBG() for COMI, too (just like for FT). This fixes verb text being cut-off at the bottom (like a 'g' was cut off at the lower end).
