What changed in EDuke32, build by build

Add "swaparrays" command, which performs a pointer-swap on arrays of the same storage class.

Factor out the parsing of gamearray names.

Remix resizearray in the following ways:

Implement the copy command for GAMEARRAY_BOOLEAN.

Fix two regressions completely breaking the correctness of the copy command, introduced in r6343.

Ensure that anywhere the def parser takes a tilenum or palnum accepts defined tokens in addition to integer literals, if it doesn't already.

Move some of the more commonly used CON functions to the top of the switch in VM_Execute(), and promote some of the loop's variables to native_t. Unfortunately, Visual Studio's new clang-format integration took it upon itself to reformat everything. Use diff -w.

make setting a sector's .wallptr call setfirstwall() instead of setting it directly and corrupting the map

actors.cpp: improve SE_11_SWINGING_DOOR detection and handling of players that block a door's path

Revert r6526 and r6527. This restores the longstanding behavior of the killit command, and setting sprites' xrepeat to zero, to not actually delete sprites unless their statnum is STAT_ACTOR or STAT_MISC. Be sure to set a sprite's statnum to one of these statnums if you want it to be deleted.

Slight cosmetic cleanup

Implement graceful playback failure

Fix MIDI playback on non-Windows platforms

polymost_drawpoly(): fix issue where mirrors wouldn't update the depth buffer

G_HandleMirror(): When choosing which mirror to render, only choose from mirrors that are potentially visible.

engine.cpp/.h: clean up & fix lintersect(). Additionally, add support for finding intersections of collinear line segments.

polymost_bindPth(): Fix issue where non-indexed colour, non-hightile textures (including those with polytintflags HICTINT_USEONART or HICTINT_ALWAYSUSEART) would not render correctly while r_useindexedcolortextures is set.

Incrementing ud.executions is now done in app_main() instead of CONFIG_WriteSetup() so that it is only incremented once per execution.

Dynamic tilepacking for indexed colour textures

ud.showfps > 2 now shows Game Update time and Game Update & Draw time (along with the min & max Game Update time) for easier performance analysis

polymost_resetVertexPointers(): remove erroneous glBindBuffer call

Amend r6870 and r6871 to only apply in WW2GI mode.

Revert r6870

Ignore cache size setting in .cfg if the value is less than the hard-coded default

Very light sound cleanup

Add quick save and quick load to the keyboard configuration menu

Bump the default cache size to 96 MiB.

Disable S_ClearSoundLocks, preventing sounds from being marking purgable, and causing them to get prematurely evicted.

WWII GI: Remove the hack/approximation for the bazooka display code because one of the general weapon system fixes made it work incorrectly, and also made a direct port of the original code work correctly. Accuracy FTW!

Fix some printf warnings.

WWII GI: Fix the chaingun replacement to always reload even if you continue holding down fire.

WWII GI: Fix the chaingun replacement to not fire in bursts of 3 per fire button press.

WWII GI: Fix mistakes in our version of the weapon display code.

WWII GI: Update the default values of the weapon gamevars to correctly match the original game.

Direct cache1d error messages to log instead of stdout

Add 'P' hotkey to change palette in tile selector, and clean up the info at the bottom of the screen a bit

second attempt at preventing extra wall points from being inserted on some walls with the batch point insert tool

in tile selector, make backspace set palette to 0
