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.

Now, if more than one sectors are affected, always move them by the same
amount. That is, if one of them would be sticking against the other side,
don't move the rest. Another change consists of determining the z delta

effector sprites would be raised one time too much, preventing them from
being lowered the next time.

- collectsectors <<array_to_collect_sectnums>> <initial_sector> <<num_collected_sectors>> <sector_filtering_state>
The latter does a breadth-first search starting from an initial sector and collects nextsectors only when the filtering state, given a sectnum as RETURN input, writes a nonzero value into RETURN. As a usage example, a.m32 includes the state 'collect_teleporting_sectors', that collects all sectors containing an SE7 and highlights them afterwards. This way, it should be possible to retrofit old maps with TROR by distributing small scripts that do most of the work (right now, joining has to be done by hand, though).
* corruption checker: for the 'nextwall inconsistent with nextsector' corruption, suggest an alternative fix by searching fitting nextwalls and changing the nextwall of the corrupt wall (as opposed to the nextsector). It will display with a leading '?' in the listing, and can be demanded by suffixing 'corruptcheck tryfix' with it. For example,
corruptcheck tryfix 9-21 ?

* 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.

* 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

* rudimentary TROR support
* free mixing of multi- and single-tile pskies
* Don't cull models behind you. That is, treat them like floor sprites in that respect. This way large models like corpses don't disappear from the view unexpectedly.
Classic:
* tweak the last row and column of the translucency table so that e.g. a transparent sprite against a FANSPRITE wall doesn't show up purple (only if Duke3D table is found)
Misc.:
* fixes TROR-nextwall corruption when deleting sectors
* tile selector 'goto' now has also completion
* I forgot a file for the non-OpenGL build last time

* make it possible to duplicate from extended sectors; all extensions are cleared from them
* lazy hightile loading in tile selector can now be disabled in mapster32.cfg
* fixes USE_OPENGL=0 build

* more useful auto-red wall feature: if no structure-changing operations have been applied after highlighting and duplicating, now also paste 'visual' fields of outer walls (this is one example of the use of a system that temporarily keeps track of nextwalls for former red lines)
* multi-pkies now have individual parallaxyscale

* support for free mixing of multi- and single-tile parallaxed skies in classic
* make visibility independent of yxaspect and viewingrange in OpenGL modes
-- editor:
* when dragging walls, restore pixel width after that (only for the left and right walls of pointhighlight, and its nextwalls, if any)
* pasting on walls and auto-aligning them now carries over a few more fields
-- fixes:
* visibility in OpenGL modes wasn't incremented gradually (regression due to making 'clamp' an inline function instead of a macro)
* memory corruption due to calling qlz_compress with less than the recommended surplus storage of 400 bytes
* decorative sprites in the mirror showing non-flipped
* make the subway SE message (much) more helpful by showing which sector the game considers to be the track sector

* Polymer light access to m32script (light[<lightidx>].<field>). As an application, provide a state 'insertlights' that takes the currently active lights and puts them into the map as SEs (e.g. for maphack recovery).
* Prototype of a mechanism to gray out certain portion of a map, making them inactive to various, but not all, editing operations. Highlighting a set of sectors and pressing Ctrl-R will make the Z bounds be [(least ceiling z), (greatest floor z)] of all selected ones, pressing Ctrl-R when no sectors are highlighted will reset them. Not sure if it's for production use at this stage...
* The 'align walls' feature [.] now has three independently toggleable behaviours: recurse nextwalls (toggled when Ctrl is pressed), iterate point2s (disabled when Shift is pressed), and also copy pixel width (toggled when Alt is pressed).
* Make shades clamp instead of overflowing in the editor
Fixes:
* crash when carrying out certain operations on walls with xrepeat 0
* the Pause key on linux. Also make demo recording start on Shift-ScrollLock because ScrollLock alone is too easily pressed when pausing
