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.

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.

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.)

renders the entire screen every frame, but it tries to update (i.e. copy to
the backend) only the parts of the screen that actually changed. At least
approximately so.

over the past few weeks, except for g_sword2. (Of course, this doesn't
necessarily make the code any prettier, but we can work on that later.)
svn-id: r11309
touches a lot of the code, of course, and adds yet another global variable
(temporarily, I hope), but everything still seems to work.
Knock on wood.

only uploaded to the backend if fadeNow == RDPAL_INSTANT. Otherwise, assume
that FadeServer() will do it for us, eventually.
I think this is the correct behaviour, and it prevents the bug where the
unfaded room image might flash by briefly when moving the mouse while
changing rooms.

for the making it a timer handler. This should eliminate the occasional
glitches I've been seeing with fades not being completed.
I'm also hoping that it will fix the problem where the game would sometimes
hang when moving between rooms. I know that at least once when I had that
happen to me the game was busy-waiting for the palette to fade.
At the very least, it's one place less to worry about thread-safety in.

under the shack), plus some other cleanups. The s->blend & 0x02 case looks
bogus to me, but I don't know where it's used and I can't see that the
original did it differently.
