Cosa è cambiato in EDuke32, build per build

Remove NULL checks before calling free(): they are unnecessary as per the C standard. Other cleanup includes factoring code into DO_FREE_AND_NULL() macros.

Add basepalette, palookup, and blendtable tokens.

Prevent tilefromtexture from ever assigning index #255 (the transparent color) to the processed image.

Internally, work with 24-bit palettes instead of 18-bit.

Restructure the basepaltable subsystem to support up to 256 palettes and use dynamic allocation like palookup and blendtable.

Don't error out when lookup.dat can't be read.

Restructure loadpalette() so that read errors are not immediately fatal and enforce that the necessary parts have been loaded in E_PostInit (after loaddefinitionsfile()).

Add E_PostInit, called from the game after loaddefinitionsfile().

sd

call update_highlightsector() after 3D mode RCtrl+RAlt.

Update the precompiled Windows libraries: libogg 1.3.2, libvorbis 1.3.5

Merge compat-from-mingw-w64 into compat-to-msvc since we dropped support for mainline MinGW32, and add dll_dependency.S so we don't need to build the libs with "-fno-stack-check -fno-stack-protector -mno-stack-arg-probe".

Reinstate the printing of quote 121 when DNKEYS is used.

RCtrl+RAlt (+['] or [;]) selects sectors in 3D mode, by The Mechanic.

in manual member editing, Shift+ENTER allows toggling individual bits

amend action's viewtype -8 to be more in line with the others.

after playtesting with Esc+[T], break from the key polling loop.

allow viewtype -8 for 'action', meaning to x-flip the shown sprite.

Amend r5330.

Fix GTK build.

Fix USE_OPENGL=0 build.

Mostly revert r5326, and instead restrict the starting and stopping text input to touch devices where we need the on-screen keyboard to appear. This maintains the bugfix on targets with a physical keyboard.

Fix the Custom game content directory startup window option loading the folder alphabetically previous to the one selected when the "autoload" folder is present.

Add EVENT_PREDRAW2DSCREEN.

Improvements to the MSVC project.

don't enable/disable SDL text input.

don't repeat #ifdef/#endif for SDL_{Start,Stop}TextInput().

SDL2 layer: handle all Ctrl+[A-Z] keys passed to OSD_HandleChar().

fix oob write for Ctrl+K ("delete all to end of line").

in test/helixspawner.lua, make COLOR a global variable. DONT_BUILD.

add config variable 'corruptcheck_heinum'.

make BOUNCEMINE spawn FRAMEEFFECT only if moving horizontally.

Revert r5316 which completely broke BOUNCEMINE.

Pragma fuckery. DONT_BUILD.

don't spawn FRAMEEFFECT1 for BOUNCEMINE.

engine.c: use swapptr() instead of swaplong() in two cases in drawmasks().

don't redundantly adjust globalcursectnum in polymost_drawrooms().

in DNCOORDS display, show x/y/z for VEL + ps->fric x and y components.

fix displayed viewscreen when its x/yrepeat isn't evenly divisible by 4.

add DEBUG_FRAME_LOCKING functionality.

fix unbalanced begindrawing()/enddrawing() pair in printext16().

Fix various, but not all warnings.

re-enable changing position in 2d mode with the right mouse button when dragging selected objects

fix frame locking issue with 2d3d mode, crash when toggling bottom texture swap, issues with drawing certain types of walls.

fix display of pal 4 sprites in 2d mode.

fix 3d mode status messages being overwritten with position/ang/horiz readouts.

fix unreadable status messages in 3d mode when working with a palette that doesn't align to Duke3d's color layout.
