What changed in EDuke32, build by build

We do this by messing with the GL texture that gets uploaded for CHAINGUN. Since this is implemented on the engine side, the static value for CHAINGUN (2536) is used, and the tile dimensions are compared to 211x55 to have a little confidence that the tile wasn't overridden by a mod. Hack indeed.

Currently, the FPS determination is based on libvpx's vpxdec.c code, which uses the FPS provided in the IVF file in one case, and simply sets it to 30 FPS in the other. For the first case, a "correction" is carried out for something which the comments suggest to originate from other (old?) VPX encoder versions.

When LShift is pressed and the mouse is over a linking sprite (as determined by the tag labeling system), lines are drawn to all other sprites, and pressing [ or ] will cycle these then. False positives and missed sprites are possible. Additional changes: - consider SE 31 and 32's lotag to NOT be linking, since the ACTIVATOR is what matters. The original maps are inconsistent there. - When pressing Alt+[ or Alt+] and there are no corruptions, say so instead of doing [ or ].

This event is useful in certain circumstances where you want to skip a menu/screen value and the design of the monster switch statement would require the M_ChangeMenu() call to be intercepted or the unwanted screen will flash for a split second.

These control the maximum difference in height between two sectors that the player will automatically traverse without needing to jump. The latter controls the special case when the player's sector's lotag is ST_1_ABOVE_WATER or p->spritebridge == 1. BYTEVERSION bumped.

* Centralize optimization strategies in Makefile.common. This required moving detection of $(PLATFORM), which makes sense if we work on the paradigm that Makefile.common is for generic compiler setup and Makefile.shared works with libraries and things closer to the engine and game code itself. * New Makefile variables OPTOPT (Optimization Options) and CUSTOMOPT (Custom Optimizations). OPTOPT by default contains -march, -mtune, etc. Setting this variable from Make invocation will blank these. CUSTOMOPT (Custom Optimizations) works the same but in an additive fashion, overwriting nothing. Technically CUSTOMOPT could stand for (Custom Options) and include any additional parameters sent to both linker and compiler. * Factor out literal names of the main executables. * The build process now prints assembler (if NOASM=0) and linker settings in addition to compiler settings.

This commit also adds the NOTELEPORT sprite flag, which of course prevents sprites from teleporting.

And hook them up to cstat 128 (half-submerged, 'c' in mapster).

The attribute is set per tile from DEF: either texhitscanrange <begintile> <endtile> or tilefromtexture <tile> { ... texhitscan ... } (As a special case, the list may only contain "texhitscan", in which case the texture is not changed.) In passing, do some cleanup for "tilefromtexture" DEF parsing: the list tokens should now be accepted in any order, and errors don't appear in the middle of the list parsing.

Also catch some other literal SEs and statnums.

Submersion only happens when the upper sector has lotag 1 and its vertical neighbor has lotag 2 (this can be useful to create non-submergible above-water sectors). Currently, only the player is handled. On the implementation side, the water handling code is split into P_Submerge() and P_Emerge() preparing the "teleportation", and P_FinishWaterChange() for the finalization.
