What changed in EDuke32, build by build

Because: 1) It used to be like this; 2) guard against bad CON input.

Encountered with Scent.map. Since the SE21 are deleted after they have been used, the search for them in the ST28 code in sector.c may come up empty, in which case sector[-1] would be accessed.

This was discovered because viewscreens (TILE_VIEWSCR) ceased being drawn with the MAXTILES increase (reported by Hank, who also did the bisect).

Internally, the last argument to neartag is now a pointer to a function int32_t (*blacklist_sprite_func)(int32_t i), which is supposed to return 1 if sprite[i] should NOT be considered for hitting. This is now used in the hard-coded neartag() calls in sector.c, but not in any way in CON (there's neither a C blacklist function provided, nor is there a possibility to define one in CON). There, all sprites with picnums >=1 and <=10 (i.e. the effectors) will be blacklisted. This remedies problems where such sprites would get in the way of switches. Note that a whitelist approach (only consider a predefined set, namely those picnums which will be checked afterwards) has back-compatibility implications since people may have used e.g. lotagged window sprites to cover a switch. Also, the >=1 to <=10 range is [sic] (the static, not dynamic values are used), since anyone redefining effector picnums is clearly out of their mind.

- RENDERER SETUP is now also accessible from classic, with only 2 options: 'aspect ratio' and 'ambient light level' - remove the latter option from the VIDEO SETUP menu - When compiled with OpenGL, the aspect ratio option cycles between 3 states: r_usenewaspect=1 (the modern way), and r_usenewaspect=0 but r_widescreen=0/1. In non-GL builds, there are only 2 states. - don't display black translucent overlay in COLOR CORRECTION menu

This makes more sense because the game selector draws the names with uppercase letters and the hotkeys to jump to a map starting with a particualar letter aren't case sensitive, either. Mapster32's selector will still display maps starting with upper case first.

The bulk are whitespace changes; the only exception is a "if (expr) { stmt; }" --> "if (expr) stmt;"

Also, there's a "ladder" that passes through a TROR portal, and the mirror in that map has been fixed for the classic renderer.

The reason was that drawmasks(), which was where the resetting of the fake RoR textures happened under Polymer, can be called from polymer_displayrooms() when mirrors are present. I was assuming that drawmasks() was only ever called after the 'main' drawrooms and that hence the sequence of fake RoR tile tweaking was set, reset, set, reset, ... which it was not. Now, do the resetting explicitly after every drawmasks() in the editor.

I find this cleaner for two reasons. First, lotags won't get in the way of neartag(), so that doors and switches near constrained TROR walls can be pushed. Second, this removes the information leak so that CON coders aren't tempted to read that values directly before a proper API for that comes along. When writing out a map in-game (e.g. with dndebug), restore the respective members so that it can be loaded in the editor again.

getzrange() returns the floor rather than the sprite if their heights are equal. Now, make an exception for extended floors (analogously, ceilings).

- guard cansee() against negative sectnums (return 0 immediately), since it's often called with the player sectnum as one argument - in resetpspritevars(), don't inset APLAYER sprite if sectnum < 0, which can happen if a map is started in void space accidentally (e.g. from the editor) - two checks before accessing sector[] with a player sectnum

Uncomment #define DEBUG_VALGRIND_NO_SMC in duke3d.h to be able to valgrind --smc-check=none (or the default stack-only) with Polymost and Polymer renderers.

This fixes a bug in passing: 'int32_t j' was assigned to as a temporary inside one instance of the code, but used as if it were the previous sprite index further on. Would only happen with projectiles that "work like" both SPIT and RPG_IMPACT.

Internally, there's a new function fade_screen_black() that implements the fading more efficiently than calling rotatesprite for classic, and uses tile 0 (assumed to have at least 64x32 size) in the GL modes. The black background of the user map selector is still done with rotatesprite and tile BLANK in every renderer.

The problems still remains that rotatesprite behaves differently in classic and OpenGL modes with clipping boundaries specified (and maybe in some other cases)

The implementation uses the recently introduced updatesector_onlynextwall when setspritez fails.

Also a couple of other cleanup lines... might need more though, I'm not sure it's all good there.

Internally, updateanimation() now takes a third parameter 'lpal'.
