Release 105-1214

The changelog since release 105-966 until release 105-1214, which happened in October 2022.

Caveats

there is now only one UnitUnitCollision event for each unit pair, and return values from UnitUnitCollision are now ignored!
vsync springsettng now defaults to -1
ships now obey upright = false when pulled out of water (still always upright when floating).
killed most of ARB shader fallbacks

multi-threaded unit steering and collisions.
there is now only one UnitUnitCollision event for each unit pair, and return values from UnitUnitCollision are now ignored!
added modrule, movement.groundUnitCollisionAvoidanceUpdateRate, for controlling steering performance vs quality tradeoff load. Reduce to get better quality at the cost of perf. Default value is 3 for cycling through all units over 3 sim frames.
added modrule, movement.unitQuadPositionUpdateRate. Similar perf tradeoff to the above, but affects collision accuracy (incl. with projectiles). In particular, if this value isn’t 1 then sometimes beamlasers/lightning can visibly ghost through units. Defaults to 3.
added modrule, movement.maxCollisionPushMultiplier, limits the speed (as a multiplier relative to their base speed) units can push each other at. Defaults to infinity/unlimited.

add animated “flipbook” CEGs: animParams = "numX, numY, animLength". Enabled for BitmapMuzzleFlame, HeatCloudProjectile, SimpleParticleSystem and GroundFlash.
some semi-transparent objects can cast colored shadows
fixed smoke-trails with a non-standard smoke period
/dumpatlas for now only works with proj argument to dump projectiles atlases to disk

ships now obey upright = false when pulled out of water (still always upright when floating).
added upDirSmoothing to unit def so units could update their upward vector smoother than by default
floating mobiles can be built over seafloor slopes

add Spring.SetFactoryBuggerOff(unitID, bool? active, number? distanceFromFactoryCenter, number? radius, number? relativeHeading, bool? spherical, bool? forced) → bool active. Forced means it also asks push-resistant units to move. Everything is optional.
add Spring.GetFactoryBuggerOff(unitID) → active, distance, radius, relativeHeading, spherical, forced, same units as above.
add Spring.BuggerOff(x, y = groundHeight, z, radius, teamID, spherical = true, forced = true, excludeUnitID = nil, excludeUnitDefIDArray = nil) → nil, for standalone bugger-off in-world (like happens when units stand on a construction site).
/debugcolvol now shows factory bugger off, in cyan. Standalone bugger off not shown.

add Spring.GetPressedScans() → {[scanCode] = true, [scanName] = true, ...}, similar to Spring.GetPressedKeys but with scancodes
add Spring.GetKeyFromScanSymbol(scanSymbol) → string keyName that receives a scancode and returns the user’s correspondent key in the current keyboard layout
add wupget:KeyMapChanged() → nil callin for when the user switches keyboard layouts, for example switching input method language.

add Spring.SetBoxSelectionByEngine(bool) → nil. If set to false, engine won’t apply selection when you release the selection box.
add Spring.GetSelectionBox() → minX, maxY, maxX, minY (sic) returning the screen coordinates of the selection box. Nil if not dragging a box.

lots of engine internals (in particular, fonts) use modern approaches to rendering. Expect speed-ups.
applied more robust algorithm of culling shadow projection matrix. The net result is that shadows should not disappear any longer on small maps, at oblique camera angles, etc.
allow skipping the use of Texture Memory Pool to save ~512 MB (by default) of statically allocated memory. Note this might be detrimental due to possible memory fragmentation. See TextureMemPoolSize springsettings
removed most of the sanity checks from window positioning code (reverted back to 105.0 like code). Now the engine won’t resist to resizing the window as the user/widget wants. There are still some rules in place, but they shouldn’t be too restrictive.
FontConfig should be more robust upon failure and don’t crash that often on FC errors
fix multiple camera issues.
fix the hardware cursor on Linux/Wayland.
fixed incorrect cubemap texture mapping

add DrawGroundDeferred callin such that bound g-buffers could be updated from say game side decals renderer.
projectiles transformation matrices are now available through LuaVBO

Added the following GL. constants:

add Spring.GetSyncedGCInfo(bool forceCollectionBeforeReturning = false) → number usage in KiB. Use from unsynced to query the status of synced memory occupation and force garbage collection
introduced RapidTagResolutionOrder option to control priority of domains when resolving rapid tags in case multiple Rapid mirrors are used at the same time.
/dumprng switch to tap out the state of synced RNG, works similar to /dumpstate
skirmish AI interface: add FeatureDef_isAutoreclaimable
fix the 1 second pause/freeze players experience when a player or spectator disconnects from the match.
fix SaveLoad hang in case when AllyTeams > 2 and one or more teams died.
fix SaveLoad memory leaks.

add options to override rapid and springfiles url.
add option to download from Rapid without using streamer.cgi, but files directly. See https://github.com/beyond-all-reason/pr-downloader/pull/9
improve file IO performance by multithreading it (big performance boost on Windows)
fix handling of unicode paths on Windows
fix finding and loading of SSL certificates on multiple Linux distributions (on Windows also switches to system certificate storage)
