Cosa è cambiato in EDuke32, build per build

The code has been factored. Additionally, 32x32 is used on Windows with SDL_MAJOR_VERSION==1, while 48x48 is the default. See: http://www.libsdl.org/cgi/docwiki.cgi/SDL_WM_SetIcon

This introduces winbits.[ch] in the engine, containing layer-independent code migrated from winlayer, including nedmalloc, ebacktrace1, OS version detection, and high-resolution profiling timers. sdlayer has been expanded to include the code from winbits under _WIN32. All uses of RENDERTYPEWIN in the source have been examined and changed to _WIN32 (or removed) where the block in question is layer-independent.

This needs improvements to bring it up to par with winlayer, but it is functional. In particular, a good amount of code from winlayer could be used for both layers, including the profiling timers, the version printing code, and the hInstance and hModule sharing. Known problems: the mouse cursor is not trapped, and the game starts before the startup window shows options.

Loops are controlled by two tags in the Vorbis Comment, both in PCM samples. LOOP_START holds the beginning of the loop, the position to which playback returns at the end of the loop. LOOP_END is optional; it holds the end of the loop, after which the game seeks to LOOP_START. If undefined, the end of the OGG is the end of the loop. The primary purpose of LOOP_END is if you want to give your file a proper ending for listening outside the game. To preview a looped OGG you have assembled, give it a ".logg" extension and play it using the vgmstream plugin for Winamp or foobar2000.

So that symbolic tile names can be used when searching maps.

The redundant ones are in code like this: s->cstat = (int16_t)32768; Because the value is eventually converted to the type of "s->cstat", any casts to integral types having at least as many bits are no-ops, signedness being irrelevant due to (probably any two's complement arch targeting compiler's) bit-pattern preserving semantics of these conversions. The now incorrect one is: if (lotag == (int16_t) 65535), "int32_t lotag" being read from a wall or sprite struct directly earlier. Now, with these members being unsigned, and (int16_t)65535 equalling -1, the check always fails. The correction fixes normal switches having such a lotag ending the level immediately. In short: integer casts before assignments are unnecessary, those in reads highly relevant!

Rewriting them in the obvious way, i.e. by casting the expression to int16_t first. (That is, this commit is the reverse of r3174, but with casts applied.) This fixes at least one regression: a FIREEXT with a hitag of 0 should not be linked with same- (that is, zero-) tagged SEENINEs or OOZFILTERs. Mind the corner cases!

- provide functions instead of messing with CONTROL_*Binds directly - comment out a few more unused functions - make clear what memory (alloc'd or const char *) 'keybind' members use - for keys with no name, use "<?>"

This function also changed: it doesn't handle floor-aligned sprites now, and the z offset is returned instead of set by pointer.

Using non-keypad [-]/[+] or LMB + mousewheel, it was broken when a void tile was in between.

This means that the internal change done to these sprite members in r3159 is hidden from CON for backward-compatibility purposes. Note that .cstat and .{ceiling,floor}stat aren't touched, and will return unsigned values to CON.

Also, add a missing "pragma pack(pop)" to build.lua.

I think this may fix some negative "non-profiled overhead" that I have been seeing.

- Eliminate use of the C++ standard library from arttool. I improved some of the program's workings but it continues to corrupt my art files in certain circumstances. (Note: Not a regression; it happens with previous revisions.) - Construct "make utils" for the game side following the pattern of the engine. - Move ivfrate to this new distinction. - Minor Makefile cleanup and tweaks, mainly to facilitate CLANG=1 and to formalize text output in special cases.

I think there's also a fix for the CON precache system breakage in here (lost it in my local tree when I started getting the C++ build working in MSVC, sorry!)

Specifically, if the first wall of the sector-to-split is to the left or right of the *start* of the splitting line AND the sector has no TROR extensions, make these two the new nextwalls of the respective split sectors.
