Also, the caching of datafiles depends on the memory usage now, not on the number of screens that the player entered in the meantime.
The old behaviour made the engine run out of memory on the PS2.

classes: Screen and Mouse. Screen handles most of the drawing, except the
mouse cursor and in-game menus.
The old Graphics class is no more.
I've also fixed some "reverse stereo" regressions from the first part of
the restructuring.
I'm not sure what the next step will be, but hopefully it will be smaller
than this one was.

the same thing as one for each music stream. If both music streams are
playing music from the same CD, they will both take turns at using the same
file handle.
The only case where both file handles are used is when music from one CD is
fading in while music from the other CD is fading out. Which of course can
only happen if you play the game from hard disk. If the game has to ask for
the other CD, it kills the music immediately.
The reason for doing this is that there was some concern about whether
having two file handles open to the same file was portable or not. I don't
think that question was ever fully answered, so I avoid the situation.

In this first step, I have moved all opcode functions into functions.cpp,
instead of having them scattered all over the place.
To get things to compile again, I had to rewrite the overly complicated
sound effects handling. It's much simpler now.
The next step will be to move any non-trivial code out of the opcode
functions and into the appropriate object. This, I hope, will make it
easier to create well-separated objects, instead of the current mess.
I also want to tear down the artificial boundary between the main directory
and the "driver" directory. We already have a cross-platform layer; there's
no need to have yet another one. (Actually, the rewriting of the sound
effects code took one first step in this direction.)
At the final stage, I'd like to get rid of the "drivers" directory
completely, but I'll probably need some help with that if I want to
preserve the CVS history of the code.
Things will probably be a bit bumpy along the way, but I seem to have
reached a point of relative stability again, which is why I'm commiting
this now.

They're generally the largest resources in the cache by far (though some
ANIMATION_FILE resources are about as big).
I still don't know how much benefit there is to resource caching, but some
of it is definitely needed, or the game won't work properly. Oh well, as
long as no one complains about the extra memory usage...

command, would close the global script variables and player object
resources, without reopening them again. This made them fair game for the
resource expiration mechanism. The player object is probably referenced
often enough to stay alive, but the variables died on me pretty quickly,
causing ScummVM to crash.
I've also added a "reslist" debug command to make this sort of things
easier to spot. By default it only lists resources with refCount > 0. Use
"reslist 0" to see all the cached resources as well.

or presses a button. This is how displayMsg() was always used, so the only
difference is that the code to check for events is no longer outside the
function.
In the process, it turned out that removeMsg() was probably unnecessary so
I have removed it. May cause regressions, but we can deal with them later.

our other engines do this, so there is little reason for BS2 to. I did add
a filtering mechanism so that mouse button releases and scroll wheeling is
ignored during normal gameplay, but I don't know if that was necessary
either.
Since this left little more than an empty husk where the Input class used
to be, I've eliminated that class and buried its remains in Sword2Engine.

to keep its own copy of the sound data. It could be even further simplified
(I don't really see any reason for having two different sound queues), but
I seem to have reached a point of stability here and I don't want to jinx
it by making further changes yet.

it's Logic::_scriptVars[ID] instead of just ID. Apart from looking cool, it
makes it much easier to tell the difference between variables and constants
when looking at the code.
Of course, this sort of sweeping changes is jolly good for introducing
truly weird regressions, which is why I waited until after 0.6.0.

GF_DEMO in functions.cpp, but I plan on rewriting that function soon so I
don't want to touch it right now.)

Added tentative workaround for the bug (a script bug, I think) that causes
the game to hang when examining the lift at the top of the pyramid.

still uses it are the engine's global variables which, on the other hand,
are used *everywhere*.
I'll have to think some more about those. I guess I should take a closer
look at how the other engines handle them. (That goes for a lot of things
by the way.)

If a cluster file isn't found the resource manager will first check if it's
one of the files that it expects to find on the hard disk. If so, it's
considered a fatal error.
Otherwise it will present the user with an "Insert CD1" or "Insert CD2"
message, just like the original did. Unlike the original, the user will
have to press a button or click the mouse to indicate when he's done. I
don't know if we even can detect the CD automatically in any portable way.
As far as I can see, we'll need at least two separate path settings for
this to actually work: one for the HD install directory, and one or two for
the CDs. The file that are supposed to be found on the HD are only on one
of the CDs, so the amount of CD swapping would probably be unbearable
otherwise.
As a consequence, I haven't actually tried running the game from CD yet.
By the way, the old caching code has been removed completely now. All it
did was to copy the cluster file to HD for faster access. ScummVM never did
that, but so far no one has complained.

and removed some of the references to global variables.
At this point I believe everything in the main game engine has been moved
into classes - not necessarily the correct ones, but still... However,
there is some stuff in the driver directory that need to be taken care of
as well.
