What changed in EDuke32, build by build

- fix an earlier 'oops': make highpals load correctly again - maphack lights shouldn't be double-loaded now - slight tweak to the loading screen fadein/out timing - two bound checks - make some variables static in engine.c

which switches have been hidden in the original and user maps. One is to make it face a wall, and another is to 'embed' it in e.g. the floor, like the monitor with the burning fuse in E4L1. Both kinds show up when the switches are rendered as models, revealing the secrets that the mapper sought to hide. My proposal, implemented in this commit, is to apply a heuristic for such switches at premap and make them invisible (set cstat bit 32768). The conditions are re-checked during the game in case there is a switch coming out of the floor, for example. A new spriteext bit is used for this feature.

The two bugs are: - RPG projectiles don't pass through water - can't emerge from slime in bobsp2 * Coalesce Polymer lights that are at the same position for FIRE-like sprites so that only one light is actually generated. This is good for usermaps that have multi-sprite fires, like bobsp2 again.

* fix 'squishing' when taking off shrunk (the reason was TROR game code using updatesectorz) and a potential sector[-1] access

by using setspritez() instead of setsprite() for the sectnum updating. * Change 'yax-nextwall(0/1)' to 'upwall/downwall' in the corruption checker, makes it much nicer to read.

* make Ctrl-Alt-A (formerly 'toggle inner gray walls') now remove all gray walls entirely in 2d mode * make r_usenewaspect enabled by default

* fix breaking out of 'switch' blocks and compilation of the 'default' case * Have a way of assigning 'special function' menu [' F] entries to script states. Writing a string literal after the state name will register the state under that name. Menu names are limited to 24 characters and it's possible to have up to 16 of them. * new branching command 'ifinteractive', true if a state runs from the menu mentioned above. * new command: getnumberfromuser <<retvar>> "query_string" <maxnum> <flags> See 'state collect_teleporting_sectors' in a.m32 for a combined usage of the new functionality.

* helper feature: when shade preview is enabled, the ceilings and floors of highlighted sectors are shown in pal 6. This makes it possible to highlight the TROR-joining candidate sectors in 3D mode using e.g. 'sethighlightsector searchsector 1' while aiming at the respective ceilings and floors, and get visual feedback. * when failing TROR-joining early ('no consistent joining combinations found'), print to the console why it failed. * more Makefile.deps updating

* New shade/visibility calculation code, which is activated with 'r_usenewshading' (on by default), and is closer to the classic look. Also tweak the FOGSCALE macro to have approximately the same fog distance with all renderers. * Mapster32: END modifier to RShift. If it's pressed when RShift is released, sprites which are in grayed out sectors are also selected; Make changing shade affect all highlighted sprites in 3D mode (when aiming at one of them). * some debug code to watch out for suspicious glGenTexture/glDeleteTextures calls, not active.

First, it is now possible to disable the memcache (which is there to cache the texcache) by setting the new cvar 'r_memcache' to 0. Do this if you're constrained on memory or getting crashes when e.g. doing vidrestart often. Also, the memcache will disable itself (and free its storage, if it's there) the first time it fails to allocate. Fix a strcpy with identical arguments in game.c and a couple of uninitialized mem accesses related to Polymer lights.
