reported by Crilith.
To elaborate a bit, the engine no longer accesses resource data through
packed structs. Instead it uses memory streams and the READ/WRITE
functions.
If data is mainly read, not written, I have replaced the old struct with a
new one with a read() function to read the whole thing from memory into the
struct's variables, and a write() function to dump the struct's variables
to memory. In fact, most of these write() functions remain unused.
If data is both read and written, I have replaced the struct with a class
with individual get/set functions to replace the old variables. This
manipulates memory directly.
Since I'm fairly sure that these structs are frequently stored as local
variables for a script, all script variables (both local and global) are
stored as little-endian and accessed through the READ/WRITE functions,
rather than being treated as arrays of 32-bit integers.
On a positive note, the functions for doing endian conversion of resources
and save games have been removed, and some general cleanups have been made
to assist in the rewrite.
Initial reports indicate that this patch indeed fixes alignment issues, and
that I have not - surprisingly - broken the game on big-endian platforms.
At least not in any immediately obvious way. And there's still plenty of
time to fix regressions before 0.9.0, too.

The various game settings are no longer stored in the Gui class. They are
stored in the class that use them.
Code that doesn't belong in the Gui class, e.g. the "restart" code, has
been moved out of it.
Afterwards, the Gui class had been reduced to nothing more than a handful
of trivial methods for invoking the in-game dialogs. So the entire Gui
class has been removed.

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.

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.

The equally experimental compression tool is in patch #854561.
Support for compressed music will require some restructuring first.

found the old name misleading (there is only one array that stores the
palette in the engine, though it could be argued that it's a copy of the
one used by the backend), and removed some code that I'm almost certain was
never used. (I've added assert()s to trigger in the cases where it would
have been used.)

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.

into the chunk of memory handled by the memory manager, not a well-defined
value. Also, it introduced a theoretical memory leak as fnPlaySequence()
wouldn't get to clean up after itself.
The correct place for this check is probably in MoviePlayer::play(), where
you can test the name of the cutscene. On the other hand, the original demo
will gladly play eye.smk if there is one, so why shouldn't we?

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

etc. to the different opcodes. Until now it has done so by casting the
pointer to an int32 (opcode parameters are represented as arrays of int32)
and then the opcode function casts it back to whatever pointer it needs.
At least in C there is no guarantee that a pointer can be represented as an
integer type (though apparently C99 may define such a type), so this has
struck me as unsafe ever since I first noticed it.
However, since all such pointers appear to point to the memory block owned
by the memory manager, we can easily convert them to integers by treating
them as offsets into the memory block. So that's what I have done. I hope I
caught all the occurences in the opcode functions, or we're going to have
some pretty interesting regressions on our hands...

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.

Renamed the resource manager's open/close methods openResource() and
closeResource() to avoid confusion. (It was I who originally shortened
their names to open() and close(), but I've changed my mind now.)
Moved more stuff into Sword2Engine.

if/when to save the settings to file, but we can worry about that later.

console from the SCUMM engine. I decided that would be easier than to clean
up the original console code.
Unfortunately there's a bunch of code that I just copied - a pretty lousy
form of code-reusal. It'd be nice if the console could be made part of the
Engine class, or something like that.
Most of the debug commands seem to be working. Some aren't relevant for
ScummVM, and some are a bit obscure so I'm not quite sure what they're
supposed to be doing.
