winlayer.c: in WM_PALETTECHANGED handling code ("someone stole the palette
so try and steal it back"), prevent calling IDirectDrawSurface_SetPalette()
with NULL arguments, causing a crash.  It's happened for me on Vista, when
initially changing from 8-bit to 32-bit mode.

Add Makefile option to use the DMALLOC (debug malloc) library.

I didn't have much success in finding bugs using it, but it works
out-of-the-box on my setup, so it may be useful in the future.

Support for the first "thumb" mouse button, called MOUSE4 in the menu.

The second one is passed to the 'mouseb' variable, but the game currently
can't map it since ud.config.MouseFunctions[] would have to be enlarged,
breaking savegame compatibility.
Works both for the Windows and SDL layers. For the latter, instead of using
the SDL_BUTTON_X1/X2 macro constants, I'm using 8 and 9, since that is what
SDL (and incidentally or not, xev) gives me for those buttons.

Temporarily disable the 'model thinning-out' feature intended to save memory.

It turns out that with model interpolation, out-of-bounds frame numbers may
be generated with thinned out models, so disable it until I can sort out
what's wrong with it.
Also, minor code cleanup.

Fix actor[].dispicnum becoming negative.

Since the original source code release of Duke3D, there was a potentially
dangerous hack where actor[].dispicnum was set to -4 to signal "this actor
should not have a floor shadow for this moment" (it doesn't really work,
if you ask me).
Now, use another bit of actor[].flags for that purpose because setting
any picnum members to negative values asks for trouble.

more internal cleanup...

the only visible change is that polymost_trytexcache (formerly two
instances of nearly duplicate code) now prints a diagnostic after
a cache miss.  The one that one is most likely to encounter is
"r_downsize doesn't match", meaning that this setting likely differs
between Mapster and the game.
