To reduce the performance impact, legacy mode will now always create flat vertex data on the fly instead of relying on the vertex buffer. This makes the CVAR mostly redundant as on anything more modern rendering per subsector will always be slower.
- rename gl_InitModels to InitModels
- add commented out support for #include in modeldefs (blocked by gene tech having broken #include statements in its modeldef files)
The precise way the clipper needs to be maintained may differ between APIs, so it is no longer owned by any render structure but instead HWDrawInfo only contains a reference.
For OpenGL there is still only one static clipper because without multithreaded BSP traversal there is no need for more.
Not only are they better placed in the common code, but they are also both per-viewpoint and not per-scene, so this is a far more suitable place and avoids saving and restoring them in the portal code.
In this case there are no means to discard the parts of the rendered sectors that lie behind the portal so it should only render the parts that are flagged as visible.
This will require some comparisons on older hardware. On my Geforce 1060 rendering the full plane with one draw call is clearly faster in all cases I tested.
At least on faster NVidia hardware, setting this to false and gl_finishbeforeswap to true gives a better experience because it reduces screen tearing - but the same setting will reduce frame rate quite dramatically on Intel and can cause bad stalls on some older GPUs when rendering camera textures.
On a fast and modern graphics card this is a lot faster than doing it per subsector but it may not be without drawbacks on older hardware so it will require some testing on older hardware.
For me Frozen Time's view over the bridge went from 46 fps to 51 fps with this change, the time saved was roughly 2 ms.

I did not consider that this is an init-only option. So changing the CVAR may not affect game behavior at all. Instead its value must be moved to some globally accessible variable on startup that never gets changed again.
- made the vid_scaleto____ commands less hacky - after finding out I could route the calls through screen->, found the correct screen-> commands, and do scaling based on the real screen dimensions
Game code should never ever call the renderer directly. This must be done through the video interface so that it can also work with other framebuffers later.
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.

This is pretty much 100% functional by now.
Hasn't been tested on platforms other than Linux yet, though.
Code definitely deserves some cleaning.
At least one version of Windows SDK (10.0.17134.0) has broken _pgmptr/_get_pgmptr()
It points to an empty string for multi-byte character set applications
GetModuleFileName() is now used instead regardless of compiler/toolchain
Added extra guard against unexpected program paths to avoid crashes

The case with forward declared class used as a parent must be handled explicitly
actor MyWeapon : Weapon { Weapon.AmmoType "MyBaseAmmo" }
actor MyAmmo : MyBaseAmmo { }
actor MyBaseAmmo : Ammo { }
This is better be made part of the 2D interface.
That would have been done long ago if it hadn't been for the totally incompatible way this was handled by the purely paletted software renderer.
Now with that out of the way there is no point keeping this code this deeply embedded in the renderer.
Although this is currently safe there is no guarantee that future refactorings will keep the current draw lists, so it's better if GLDecal used its own copy of the data.
- precalculate if a sector's floor and ceiling plane overlap. This avoids rechecking this for each single call of hw_FakeFlat.
- vertices must be marked dirty every time they change after map setup. That means that ChangePlaneTexZ must do this as well, because it cannot rely on interpolation taking care of it.
- Having a 'dirty' argument for SetPlaneTexZ's ZScript version makes no sense. If the value changes from the script side the vertices must always be marked to be recalculated.
This was all over the place, with half of it using the function and half doing incomplete checks on the underlying variables.
Also did some optimization on the IGNOREHEIGHTSEC flag: Putting it on the destination sector instead of the model sector makes the check even simpler and allows to precalculate the effect of 3D floors on the heightsec, which previously had to be run on every call and made the function too complex for inlining.
* only call hw_CheckViewArea if the result is not known yet.
* check the map up front if it even contains heightsecs. This allows to shortcut the above check entirely for maps without sector transfers and will allow further optimizations.
This should fix bug reported in https://forum.zdoom.org/viewtopic.php?

There were two problems:
1. Algorithm to select a free voice was not appropriate. Changed to a
simple "least-recently-freed voice" algorithm.
2. Sustained voices were treated as used voices and never got replaced.
Now sustained voices are preferentially replaced when there are no free
voices.
Lots of this was still laid out for DirectDraw. This removes most of Begin2D so that it can be done more cleanlz.
Note that this commit renders weapon sprites and screen blends incorrectly. Those will be fixed in an upcoming commit.
Since they mess around with the texture coordinates, these need to be backed up and restored afterward.
There was also an issue with the ValidNormal check that was suffering from imprecisions that cause walls to be skipped, so the check was removed because it was mostly pointless.

* 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.
- added thread_local to some static arrays being used for setting up dynamic lights.
Right now it's of little consequence but these will have to be maintained per thread if the render data setup is done by worker tasks.

Decals will now be processed into a list in the processing pass, allowing to use the vertex buffer even on GL3 hardware and to offload this part of the work to a multithreaded worker task.
