Cosa è cambiato in EDuke32, build per build

Requested auto-correction will place such sprites at their sector's first point.

This is really an artifact of overloading the sector fields for different uses. For copy-pasting TROR'd portions, the bug still persists.

Because rotating sectors "smoothly" by 1 BUILD ang will quickly accumulate roundoff error, this lets the user first do that as a preview and then use the manual angle rotation do carry it out for real.

This was actually broken all the time except when ALL sectors were selected (which was what I tested incidentally when I wrote the first "fix"). D'oh!

This was exposed by Clang with -ftrapv, which apparently also traps those.

Usage is from 3D mode only. When a sector (or wall) is committed to the clipboard, it (or the wall's sector) is saved, and is subsequently used when auto-aligning [;-ENTER] another sector's ceiling or floor against the reference one's. This temp. sector is reset on any structurally modifying operation except setting first walls; also, aligning extended ceilings or floors is impossible as they use .*xrepeat internally. The auto-alignment does not change picnums (this can be accomplished with the ['+ENTER] combination), but copies the orientation bits 2^{2..6} to the alignee. Afterwards, if the reference is relative-aligned, it tweaks them, so that every case where the two firstwalls are either parallel or perpendi- cular is handled correctly. It does not yet calculate the panning values.

Also factor out the code (2x) setting the alignment bits for sprites.

We were writing into a string literal. Ouch!

This checks for about every possible type of sprite list corruption and reports back with a corruption level 5 if one of the 14 validations fail.

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.

The implementation uses the recently introduced updatesector_onlynextwall when setspritez fails.

Usage: press the ['] (quote) modifier together with the PERIOD key. Aligns only the immediate upper and lower neighbors of each wall that got aligned by following point2s or nextwalls. Doesn't play well with Alt (carry over xrepeat) yet, might need two subsequent alignment passes.

How in the name of hell this could pass undetected for so long is a mystery to me.

one sector was filled and the 'clear bunch' message was displayed even if the operation was canceled.
