What changed in EDuke32, build by build

* Make the minimum resolution possible 640x480. Sometimes you'd accidentally enter something like 'vidmode 800 60' and crashes would ensue... * fix a warning

Implementation note: the so instrumented sprites use actor[].t_data[7] to hold a magic number (0x18190000 + pivot spr idx), and t_data[8] and [9] for the initial coords relative to the pivot point.

* fix memory corruption when loading a Polymer savegame using another renderer and then change to Polymer * fix possible crash in OSD_Exec() and uninitialized mem access in game config reader * move makeasmwriteable() to baselayer.c

* Voxel tweaks: horizontally scale wall-aligned ones by 5/4, make them ignore per-tile yoffset in classic (i.e. emulate Polymost; I think this is more sensible since they're not clipped to floors/ceilings anyway), make Polymost know the voxel scale * Always cull back-facing, one-sided, wall-aligned sprites (classic/Polymost), irrespective of whether it's a sprite, voxel or model. This can lead to falsely not drawing them in certain circumstances, but IMO that's preferable to visible hidden switches etc. * Change defaults for r_novoxmips to 1 and lazytileselector to 0

* When TROR-joining and sectors reachable through former red walls could need displacement, ask the user; if something is wrong with the walls of the two components to join, jump to that place and print coordinates of offending wall and its point2 in the OSD * Ctrl-TAB in 2D mode now toggles filling of the currently aimed-at sector; it's not very in sync with the rest of the controls though (e.g. some commands will potentially affect each sector that contains the crosshair) * Fill sectors slightly different so that highlighted sectors above each other are easier to distinguish * In the editor, always clear the screen to a 'rainbow' of the palette before each frame. This makes no-draw ('HOM') and accidental translucency glitches stand out more clearly * a few misc. tweaks, consistency checks, and fixes

* Mapster32 now makes sandwiches, too: select all floors of a bunch and 'extend them below'. This will put a new sector between the highlighted ones and the their lower neighbors and displace the z's accordingly. Make sure you have enough headroom. * To facilitate the above, RAlt now has two more modifier keys (checked at release time, as usual): for every sector that would be selected, END will select all sectors whose floor bunchnum equals the first (this is useful for sandwiching), and HOME will select all sectors whose ceiling bunchnum equals it (not very useful, but provided for completeness). * Sloping extended sectors is now checked more rigorously -- misc: * When deleting highlighted sectors with DEL, pressing LShift will now always delete them irrespective whether the mouse pointer is over one of them. This is useful for the cleanup of corrupted maps. * 2D drawing is slightly tweaked so that active walls always display over inactive ones

game: when entering/leaving water or slime, delay changing palette by one game tic to make it look right
