What changed in EDuke32, build by build

It works perfectly fine without it for me, and including it for no reason is just an annoyance to other people building from source.

Defines SPRITES_OF(Statnum, Iter) and SPRITES_OF_SECT(Sectnum, Iter) [The first is so that STAT_* can be substituted for Iter and it reads nicely.] Usage should be self-explanatory, but one thing to keep in mind is that the sprites that are iterated over MUST NOT be deleted.

This fixes the glitches/corruption whereever showview is used from EVENT_DISPLAYROOMS while the scene is actually rendered to a tile instead of the frame buffer, for example because we have a tilted view or "pixel doubling" enabled. Fixing it for real (i.e. so that the showview actually completes) will require more effort.

vbit was being accessed with an int32 e.g. at address 3200 when only 3203 were allocated. We simply alloc +1 byte.

This fixes the crash on Wii when looking sidewards (e.g. when dying), but makes the tilted view look more pixelated. The problem was that an attempt was made to render onto a 640x640 tile for the rotated view, but the base engine arrays were too small for that.

- make allocatepermanenttile() return intptr_t - the usual

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.

They were broken by r2666, which made their elements intptr_t instead of int32_t, but this change was not reflected in related allocation code. WARNING: players on 64-bit platforms should not attempt to load games saved with r2665 or earlier.

Note: You may encounter a crash if you try to test your map and Mapster32 is running fullscreen.

- alloc_multimapstate() helper - make g_netMapRevision a uint32 and store save->revision in sequence order (without &(NET_REVISIONS-1)) - one assert, one XXX comment, stylistic changes

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).

The default C99 mode is giving us linking errors from xdelta3.
