That is, "clang -ftrapv" builds don't abort almost immediately after entering
a level.
There are various classes of overflow bugs, needing different handling:
- Some texture mapping code was written with signed integer wrapping semantics
in mind. In some places, we're able to get away with unsigned casts.
- sometimes, we really need a wider range, like when calculating distances or
dot products
- negating INT_MIN. Here, we cast to int64_t temporarily. Note that if the
result is 32-bit wide, no 64-bit code may actually need to be generated.
- shifting into a signed integer's sign bit. We cast to uint32 here.
- in hitscan(), at the "abyss crash prevention code" comment, it's clearly
the other code that is better...
This is not merely done for pedantry, but rather makes it easier to track down
overflow bugs having a real impact on the game.

For SDL 1.2 and when building on linux, the code using
clock_gettime(CLOCK_MONOTINIC, ...) is taken over from SDL HG.
gethitickms() is a convenience function that return milliseconds as
doubles and isn't exposed in any header file, yet.

Doesn't work: indexed-color modes, gamma (at least for X11), mouse wheel,
special keys like ENTER or BACKSPACE in the OSD, probably more...
In build/Makefile.shared, we now have logic to autodetect an SDL2 installed
in /usr/local, however OS X and Wii builds follow other Makefile code paths,
it seems. Note that the matching SDL2_mixer must be used then, too.
In source/jaudiolib/src/driver_sdl.c, change the #includes from <SDL/SDL_xxx.h>
to "SDL_xxx.h". SDL wiki says this is the most portable way, hopefully this
doesn't break builds for anyone.

It's time to replace some int32s with 64-bit ints in core engine functions.
The problem is that for example, the dot product is taken between vectors that
may be the difference between two arbitrary points in a sector, so even if one
sticks to the "no blue walls" rule, that doesn't guarantee freedom from
overflows.

Those were happening when wall drawing in an upper/lower layer "closed" too
much of the "curtain" (umost/dmost) for subsequent drawing in that portal.

New Wii control defaults for the Wii Remote + Nunchuk and the Classic Controller. This includes new code added just so that the Home key brings up the menu in-game, reducing the need for a USB keyboard.
On the technical side, raw joystick access (comparable to what is available for keyboard and mouse) is now present in jmact, on the game side. (added: joystick.[ch])
Using this new raw joystick access, I replaced tueidj's hack to map A and B to LMB/RMB and D-Pad Up/Down to the scrollwheel.
I made the menus more friendly to mouse and joystick browsing by adding and unifying checks and clears for various buttons and gamefuncs. In fact, the majority of the time spent on this commit was tracking down problems that appeared with the factoring and trying to understand the menu system and the way input checks are precariously executed.
In addition, "Press any key or button to continue" now truly means what it says.
As a result of incorporating proper raw access into control.c instead of it directly accessing the implementaiton, the program *may* no longer be affected by joystick input when it is out of focus. This follows the pattern set by the mouse, and I think this is a positive change.
A small bonus: In the classic/old keyboard preset, the key for Show_Console has been changed from '`' to 'C' because '`' is taken by Quick_Kick.

This introduces a Makefile variable EDUKE32_MY_DEVELOPER_ID, which is
expected to come from the environment, so that minor disagreements/

My ID is 805120924, i.e. "helix".

Usage is from 3D mode only. When a sector (or wall) is committed to the
clipboard, it (or the wall's sector) is saved, and is subsequently used
when auto-aligning [;-ENTER] another sector's ceiling or floor against the
reference one's. This temp. sector is reset on any structurally modifying
operation except setting first walls; also, aligning extended ceilings or
floors is impossible as they use .*xrepeat internally.
The auto-alignment does not change picnums (this can be accomplished with
the ['+ENTER] combination), but copies the orientation bits 2^{2..6} to the
alignee. Afterwards, if the reference is relative-aligned, it tweaks them,
so that every case where the two firstwalls are either parallel or perpendi-
cular is handled correctly.
It does not yet calculate the panning values.

The first means that the expensive (~0.5 ms) SHGetFileInfo() calls won't inter-
fere with smooth gameplay, but files that are opened only at game-time like
sounds won't be checked. The second means that there are now less false
positives, i.e. warnings about files that would be found due to the
check-all-{upper,lower} hack.

Most of the time, Windows file name lookup is case-insensitive. Reading the
docs (see MSDN's CreateFile help, for example), it seems like case-sensitivity
can be controlled on a per-file basis where applicable (NTFS), but people
should be concerned about matching case in the DEFs/on disk *especially* in
that case.
Also, note that this hack will not always help on systems with case-sensitive
lookup.

When a file from the local file system is opened, its real file name is gotten
with SHGetFileInfo() and compared against the one that was passed. In the case
they're not identical, a warning is issued.
This is one step towards eliminating mismatched file names in DEFs etc., which
cause trouble on systems that look them up case-sensitively. However, it's not
perfect because the issue is trickier than it appears on first sight.
For one thing, this will only check the last (i.e. file) part in the path,
falsely accepting mismatched directory names. However for these, it reports
them ruthlessly, even for those names where the try-other-case hack (try all
uppercase, all lowercase) would find the correctly-cased file.

This should be more correct, since previously, the saved PNGs were way too
contrasty when looked from within a browser. Now, they'll always be
slightly darker than in-game (assuming one has a gamma greater than 1).

- don't allocate additional sector/wall storage for Mapster (saves ~16k)

Previously, we checked whether the faded palette has changed (by way of CRC)
and invalidated the textures then unless the preserve flags were set. This
however could lead to wrongly invalidating them under unfortunate circumstances,
e.g. basepal change from CON + tints at the same time before r2620 which
reverted r2232.
Now, only invalidate them if the corresponding preserve flags are clear AND
* the base palette has really changed OR
* the palette CRC changed and we were running on software gamma
The latter means that performance-killing invalidations may still happen on
GL platforms lacking HW gamma (for ATI, it's currently only disabled in 8-bit
fullscreen).
Also have a new global 'basepalreset' to fake a basepal change for
setbrightness(), currently used when changing renderers so that going from
Polymer to Polymost and back again will invalidate the Polymer textures
on the second change, potentially re-applying a basepal highpal. (Still
with me?)

This part is a mixture of the original patch and my changes. It seems like
tueidj had some trouble
1) getting OGG to work, which is why it's conditionally compiled out
2) struggling with endianness with the mixing routines? This may be also
due to him missing to define two others BIGENDIAN macros (our code is
in need of cleanup there). Note the change in jaudiolib/src/mix.c!
Because I added my share to this part, I might have actually broken sound
mixing on big-endian platforms.

MOUSE_GetButtons(): bits used are 256, 512, 4096, 8192
