GZDoom g4.5.0

• For all of Doom's fullscreen images there's now widescreen versions provided. The other games are still being worked on and will be added later when they become available. All new images were created by Nash - this does not use any of the versions from the Unity port.
• A simplified options menu is now available for quick setup of the important settings.
• New keybindings presets. Users can now choose between the classic layout and a WASD-based one
• Menu and intermission screen now scale to the original Doom.exe's layout by default.
• major additions to the menu system - animated menu transitions, image slideshows and fixed size menus can now be created.
• the console now uses the border flat as default background instead of the titlepic.
• it is now possible to fully quit the fullscreen console and get back to the title loop.
• various enhancements and fixes for ZScript.
• Interpolate positions and angles in the automap for smoother appearance
• Added $PitchSet for SNDINFO.
• allow indirections in the string table by prefixing the language string with '$$' the remaining text is interpreted as another string label to resolve.
• optimization of the patch texture checker - do not read in the entire file if checking the initial header is sufficient for rejecting it. This can speed up loading of large mods quite significantly.
• MIDS-format MIDI support
• OPUS support, courtesy of an updated libsndfile.
• libADL/libOPN update

block off the Substitute function by making it private to the 3 classes that really need it.
let TeleportSpecial universally map to Teleport when checking action special names.
apply aspect ratio compensation for all fullscreen images with a height of 200 and 400, and not just to 320x200 and 640x400.
fixed incorrect value range for particle's depth value, used for sorting.
made 3D floor damage transfers optional by adding a new flag bit (2048) and made that mode automatic for the old ZDoom-based light only transfer special.
fixed keybinding reader - before trying to load DEFBINDS the lump index wasn't reset.
removed the "no IWAD definitions found" error message because the condition it checks for is not an error.
fixed setup of IPK3's where all content is in a subdirectory.
fixed texture layer management so that each material layer can decide for itself if it wants to allow upscaling.
rewrote the hardware texture precacher to use the new texture management to properly track the data to delete.
store the Vulkan descriptor sets in the material - where they belong! Having them in the base texture object was a major maintenance issue.
store the material layers in reference counted pointers in the FGameTexture object.
major refactor of texture upscaling control. All decisions were done deep inside the texture creation code, leaving zero options to the higher level code for controlling the feature.
moved the decision whether to upscale textures up one level in the function chain. Still not the perfect place, this should be decided before creating the texture, not in the middle of the process.
disabled the selective texture cleaning in the precacher. The logic here turned out to be a serious blocker and needs to be rethought.
allocate the sprite positioning info on demand only.
Moved the raw texture handling into the texture manager as well.
moved the front layer hack for Hexen's skies to the texture manager.
moved the handling for paletted replacements into the texture manager.
use FGameTexture instead of FMaterial for texture tracking in the hardware renderer.
moved the sprite positioning info out of FMaterial back into FTexture.
scale the automap parchment to clean 320x200 dimensions.
made 'supportRemap0' an image property so that the handling for this can be taken out of the actual texture class by just providing a replacement texture for the skies.
decoupled the software renderer entirely from FTexture - it will only look at FSoftwareTexture now, all access to the texture manager has been wrapped.
texture code refactoring to consolidate multiple textures referencing the same backing image.
handle brightmaps in the main shader instead of keeping separate instances around.
added detail and glow layers from Raze.
fixed material setup which could not guarantee that everything was initialized correc...
