* the parser read numbers with leading zeros as octal, which is not wanted here
* texture lookup by file name must be forced for root directory entries.

* do not clamp panning fields for cloudy sky with the new renderer because this makes the texture jump.
The sound system may play sounds on them after their deletion - this resulted in undefined behavior. To ensure properly defined behavior the sprite needs to be retained at least as long as the sound controller may still need it - which cannot be reliably determined so it has to be kept around forever. This would be easier if the sound controller code had proper start and stop events instead of inferring what to do from secondary information.
Fixes#288.
After discovering yet another misbehaving place in the game I think it can be safely concluded that this is better left off unconditionally.
The only remaining place where this still gets checked is in nnexts, but I wouldn't expect this to work either.
Fixes#292
* Build skies need a different mesh for the dome - the one from GZDoom distorts them too much.
* made adjustment to the positioning math after redoing the mesh
* Exhumed abuses some strange effect of the original sky placement math which means the y-offsetting must be disabled for this game.
* RRRA sky initialization fixed. It must be done after setting up the tiles.
As it turned out, the triangulator only works fine for regular polygons, but creates incomplete meshes for sectors with multiple sections or some degenerate areas, which are quite common with swinging doors.
The node builder is more costly and creates wall splits, of course, but it does not create broken output for degenerate sectors so it's a good fallback.
* Reduce code repetition.
* Clamp incoming horizon when using `settarget()` methods.
* Eliminate double calculation that was occurring in `processhelpers()`.
Since these do not fully get processed sequentially the contents need to be preserved until needed.
This required getting rid of the global tsprite array. Polymost still uses a static vatiable, though, but this is only accessed in polymost-exclusive code.
* Blood's automap was not drawn at all.
* SW's automap always showed all sectors
* SW's player sprite was not rendered.
* Non-automap: Forward gotsector to the game code because there's still a few places in Blood that need it.
* Install compilers for Linux targets explicitly
* Specify compilers for Linux target by executable names instead of full paths
* Switch to latest Clang target to 11
* Use ZMusic 1.1.6
* Since f4b27bbd27, `D:/Program Files (x86)/Steam/steamapps/common/Shadow Warrior Classic/gameroot/addons/Sw.grp` was being picked up instead of `D:/Program Files (x86)/Steam/steamapps/common/Shadow Warrior Classic/gameroot/SW.GRP`.
* Fixes#289.
