- optimized the math to get a plane equation from a linedef. The original code used a generic algorithm that knew nothing about the fact that Doom walls are always perfectly vertical. With this knowledge the plane calculation can be reduced to a lot less code because retrieving the normal is trivial in this special case.
- use the SSE2 rsqrtss instruction to calculate a wall's length, because this is by far the most frequent use of square roots in the GL renderer. So far this is only active on x64, it may be activated on 32 bit later as well, but only after it has been decided if 32 bit builds should be x87 or SSE2.

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.
- removed the LastCamera logic in RenderView. This code predates the first GZDoom release and apparently was only added because back then R_SetupFrame was not fully compatible with the hardware renderer. Today it is not needed anymore.
(Is there anyway to tone down GCC's warning level? It outputs too many false positives for potentially uninitialized variables in which the genuine errors get drowned.)
- 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.
This one was particularly nasty because Windows also defines a DWORD, but in Windows it is an unsigned long, not an unsigned int so changing types caused type conflicts and not all could be removed.
Those referring to the Windows type have to be kept, fortunately they are mostly in the Win32 directory, with a handful of exceptions elsewhere.
A major part of this device's implementation details about how to handle the callback were not encapsulated by the device class at all, they were #ifdef'd into the streamer class.
This puts everything into the device class which now exposes a clean interface to the rest of the game with no special handling aside from calling two additional virtual functions that are empty for the other devices
* 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.
The approach being used here caused the entire sound system to be infested by windows.h, just to avoid copying around a handful of variables in one place, effectively preventing any compiling optimization.
Windows will now use the same internally defined structure for all MIDI processing which only for actual submission to the system player will be converted to the internal format.
Both files can now be included independently without causing problems.
This also required moving some inline functions into separate files and splitting off the GC definitions from dobject.h to ensure that r_defs does not need to pull in any part of the object hierarchy.
Most of those which still rely on ZDoom's own definition should be gone, unfortunately the code in files that include Windows headers is a gigantic mess with DWORDs being longs there intead of ints, so this needs to be done with care. DWORD should only remain where the Windows type is actually wanted.
- block creation of actors with the 'new' instruction. Unlike the above these cannot be made abstract because without ConstructNative they cannot be serialized.
This is one of two places that unconditionally pulled in all Windows headers into the GL code.
We also do not need the cruft for defining the standard integer types. GZDoom is C++11 which means that stdint.h will be present. So the madness with the definitions should be avoided to ensure that the types are always the same.
The code for constants was not optimal because the first operand of the instructions cannot be constant. This was solved by swapping it with the second choice which will always be non-constant.
The code for local variables did not allocate a new destination register and would overwrite the first parameter's variable.
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
This addresses the main issue with TObjPtr, namely that using it required pulling in the entire class hierarchy in basic headers like r_defs which polluted nearly every single source file in the project.
