What works:
- Parsing the model
- Constructing geometry (surfaces) for triangulated models
What doesn't:
- Rendering the model
- Building the vertex buffer
- Triangulating quads
This was done because the backdrop as implemented was the only texture in the entire game that had to be deleted and recreated each frame.
However, with Vulkan this would have necessitated quite a bit of synchronization with the render pipeline which wasn't really feasible just for this one single texture.
Now the texture manager can assume that once a texture was created it will be immutable and never has to change.
Ultimately all this needs is a small data table describing the geometric properties of each mode and a single Present function that calls the mode specific variants.
Code size got reduced from 50kb to less than 20kb with proper separation of the generic parts from the OpenGL parts.
Added ability to switch emulator and it's accuracy level ("enabling of 'run at PCM rate' reduces accuracy, and also reduces CPU usage")
Added draft code for future external banks support (WOPL format for ADLMIDI and WOPN format for OPNMIDI)
ADLMIDI 1.3.3 2018-06-19
* Fixed an inability to load another custom bank without of library re-initialization
* Optimizing the MIDI banks management system for MultiBanks (Thanks to [Jean Pierre Cimalando](https://github.com/jpcima) for a work!)
* Fixed incorrect 4-op counter which is still catch 4-op instruments on 2-op banks
* Fixed an incorrect processing of auto-flags
* Fixed incorrect initial MIDI tempo when MIDI file doesn't includes the tempo event
* Channel and Note Aftertouch features are now supported correctly! Aftertouch is the tremolo / vibrato, NOT A VOLUME!
* Updated DosBox OPL3 emulator up to r4111 of official DosBox trunk (Thanks to [Jean Pierre Cimalando](https://github.com/jpcima) for a work!)
* The automatical choosing of 4 operator channels count has been improved (Thanks to [Jean Pierre Cimalando](https://github.com/jpcima) for a work!)
* Added optional HQ resampler for Nuked OPL3 emulators which does usage of Zita-Resampler library (Thanks to [Jean Pierre Cimalando](https://github.com/jpcima) for a work!)
ADLMIDI 1.3.2 2018-04-24
* Added ability to disable MUS and XMI converters
* Added ability to disable embedded MIDI sequencer to use library as RealTime synthesizer only or use any custom MIDI sequencer plugins.
* Fixed blank instruments fallback in multi-bank support. When using non-zero bank, if instrument is blank, then, instrument will be taken from a root (I.e. zero bank).
* Added support for real-time switching the emulator
* Added support for CC-120 - "All sound off" on the MIDI channel
* Changed logic of CC-74 Brightness to affect sound only between 0 and 64 like real XG synthesizers. Ability to turn on a full-ranged brightness (to use full 0...127 range) is kept.
* Added support for different output sample formats (PCM8, PCM8U, PCM16, PCM16U, PCM32, PCM32U, Float32, and Float64) (Thanks to [Jean Pierre Cimalando](https://github.com/jpcima) for a work!)
* Reworked MIDI channels management to avoid any memory reallocations while music processing for a hard real time. (Thanks to [Jean Pierre Cimalando](https://github.com/jpcima) for a work!)
OPNMIDI 1.3.0 2018-06-19

* Fixed an incorrect processing of auto-flags
* MAME YM2612 now results a more accurate sound as internal using of native sample rate makes more correct sound generation
* Channel and Note Aftertouch features are now supported correctly! Aftertouch is the tremolo / vibrato, NOT A VOLUME!

Like Linux and macOS this will only support borderless fullscreen in the active desktop resolution now, which is what modern systems need.
The list of discrete resolutions has been removed as it makes no sense anymore with a fixed video mode - all the other scaling options remain active, though.
These files are not part of the actual renderer but part of the system code.
This means, for separated modern and legacy GL renderers, there still will only be one set of this, unlike everything else.
(concatenated "UMSH" signature + datafile + anivfile)
This is pretty much 100% functional by now.
Hasn't been tested on platforms other than Linux yet, though.
Code definitely deserves some cleaning.
* split gl_shadowmap.cpp into a GL dependent and an API independent part.
* gl_drawinfo must be kept around for the HUD sprite because it connects the renderer with the hardware indpendent part of the engine.
- eliminated hqresize.cpp's dependency on GL headers.
- cleaned up the logic for CreateTexBuffer so that hqresize.cpp does not need to check for software warped textures anymore.
- Slightly improve how softpoly processes portals
- Pass the vertex transform matrix via a command rather than being part of the drawer args
- Improve zbuffer drawers in the software renderer
- Misc model rendering fixes
* the MAPINFO options now get handled in g_mapinfo.cpp and g_level.cpp, just like the rest of them as members of level_info_t and FLevelLocals.
* RecalcVertexHeights has been made a member of vertex_t and been moved to p_sectors.cpp.
* the dumpgeometry CCMD has been moved to p_setup.cpp
This theoretically means that the software renderer could access this data as well - if it just had been written with a more flexible texture interface.
However, as things stand, this may require quite a bit of work to achieve.
The old organization made sense when ZDoom still was a thing but now it'd be better if all pure data with no dependence on renderer implementation details was moved out.
A separation between GL2 and GL3+4 renderers looks to be inevitable and the more data is out of the renderer when that happens, the better.
Also embedded MIDI sequencer has been disabled too as it is not needed in GZDoom
I made that to allow easier updates of ADLMIDI into newer versions without of any future troubles and conflicts

* Instead of using the red channel it now uses the grayscale value. While slower in a few situations, it is also more precise and makes the feature more useful.
* For paletted textures do not use the index as alpha anymore but the actual grayscaled color. This is again to make the feature more consistent and useful.
* To compensate for the above there is now a list of hashes for known alpha textures in patch format, so that they don't get broken.
* IMGZ is now considered a grayscale format. There's only two known textures that use IMGZ for something else than crosshairs and those are explicitly handled.
* several smaller fixes.
* the actual color conversion functions for paletted output are now consolidated in a small number of inlines so that future changes are easier to do.
Note: This hasn't been tested yet and will need further changes in the hardware rendering code. As it is it is not production-ready.
Until now each subclass of FTexture had to implement the entire span generation itself, presumably so that a few classes can use simpler structures.
This does not work if a texture can have more than one pixel buffer as is needed for alpha textures.
Even though it means that some classes will allocate more data now, it's the only way to do it properly.
In addition this removes a significant amount of mostly redundant code from the texture classes.
- added alpha texture processing to all converted classes
As of now this is not active and not tested.
Note that as part of the conversion even those textures that were working as alphatextures will not look correct until the higher level code gets adjusted.
PathExpander has been integrated into the sound font manager and PseudoMidiDevice was only used as the base class for the old Timidity++ device with the external executable.
This source has been heavily edited to remove the deep integration with the provided UI modules and to eliminate use of global variables and puts everything into a small number of C++ classes.
- moved timer definitions into their own header/source files. d_main is not the right place for this.
- removed some leftover cruft from the old timer code.
It now works the following way:
(0) - Force off (ZDoom defaults)
(1) - Force on (Doom defaults)
(2) - Auto off (Prefer ZDoom defaults - if DEHACKED is detected with no ZSCRIPT it will turn on) (default)
(3) - Auto on (Prefer Doom defaults - if DECORATE is detected with no ZSCRIPT it will turn off)

The needed headers are now included in the repo, which for these libraries is possible thanks to a stable ABI (at least on Windows, the other platforms still need to be checked but the headers only add, never remove or change existing content.)
The big advantage of this setup is that it allows building the project on Windows without any necessary setup - all that needs to be provided is the DLLs from the binary package.
This still requires some fixes for macOS and Linux. On MacOS the proper library names are missing and the ones for Linux are not verified. Both platforms should work, though, if the dynamic loading is disabled.
For some files that had the Doom Source license attached but saw heavy external contributions over the years I added a special note to license all original ZDoom code under BSD.
The idea is to have more control on the game side instead of dealing with these formats in the backend, which was done for FMod because it already had the decoders implemented.
However, with OpenAL this setup makes no sense and only complicates future extensions that can be better handled at a higher level.
Note that the Strife status bar does not draw the health bars yet. I tried to replace the hacky custom texture with a single fill operation but had to find out that all the coordinate mangling for the status bar is being done deep in the video code. This needs to be fixed before this can be made to work.
Currently this is not usable in mods because they cannot initialize custom status bars yet.
- moved testcolor and test fades into SWRenderer files.
These CCMDs work by hacking the default colormap and were never implemented for hardware rendering because they require many checks throughout the code.
Since the true color software renderer also handles them there is no point keeping them on the GL side.
This also optimized how they are stored, because we no longer need to be aware of a base engine which doesn't have them.
- enable precompiled headers for all non-system-specific MIDI devices.
- moved the native Windows and Mac MIDI devices into their respective sections in the project file so that they won't get compiled on the other ones.
* make the critical section local to the respective platform instead of polluting everything with system specific symbols.
* moved system specific class declarations into the source file instead of having them in the global header.
This commit temporarily disables the Windows system device because it cannot be done without polluting the global header and still needs a bit of refactoring.
Continuous integration is a cool thing: I completely forgot about addition of these frameworks because of my build environment which relies on static libraries and custom command line options
Like everything else related to doing standard math with SSE2 vs. x87, there's nothing to be gained here with anything but first generation SSE2 systems which are irrelevant these days.
Taking 'thespir2.wad' from https://forum.zdoom.org/viewtopic.php?f=1&t=10655 the SSE2 version is reproducably ~3% slower than the x87 version on my Core i7, which quite closely mirrors all my previous tests since 2007.
Overall this just looks like an optimization not worth doing.
- removed all pointer declarations to types from the symbols. All types must be placed into the type table which means that they can be considered static.
