I missed this part when repurposing the vboindex members to store the index buffer offsets.
However, since both indices are needed, they need another set of variables.
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.

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?
f=104&t=56682.
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.
* to do this efficiently the amount of required vertices needs to be calculated up-front
* always create the vertices in the data generation pass, not the render pass.
* added synchronisation code to the vertex buffer allocator.
Without multithreading this causes a slight slowdown, due to added processing cost. (Frozen Time bridge scene drops from 47 fps to 44 fps on my test machine.
- 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.
Actors get initialized from their defaults so anything done in the constructor or some explicit member initialization will be overwritten.
They must use their properties for setting up configurable fields and do the rest in BeginPlay.
This replaces the old redirection hackery that had to work differently for the legacy render path.
Overriding CopyTrueColorTranslated is far more robust and ensures that no edge cases can reach the GetPixels function, which wasn't the case before.

This is for mitigating the recently discovered problem with attenuated lights getting reduced in size, even on OpenGL 3+. The intent of the shrinking was to account for higher brightness of non-attenuated lights on OpenGL 2 and was never meant to be active on more modern versions.
The factor will apply to any attenuated light defined after it and will be inherited by included sub-lumps, but it will only last for the lunp it is set in.
If you have a definition for the broken behavior, AddLightAssociation
'lightsizefactor 0.667' at the top of your GLDEFS.
- added copy constructors and assignement operators to GLFlat and GLWall so that they can use memcpy instead of field-by-field copy. This actually increases performance slightly.
This is mainly for future-proofing because storing these as objects in an array not only has a negative impact when using multithreading due to longer blocking time for the threads but also makes it hard to cache this data for reuse.
This data is game critical and may only be altered by code that knows what is allowed and what not. It must never be altered by any user code ever.
However, since the SkyViewpoint actors need to set up some relations between themselves and the default sky portals the previously purely internal 'internal' flag has been exported as a new keyword.
The most frequent call using this is the regular texture creation function where this results in a pointless allocation and destruction of a temporary string which is easily avoided.
* use names, not strings, to allow use of switch/case.
* avoid creating the checksum a second time per level.
* do an early-out check for maps that do not have scripted compatibility.
They were already deactivated because with 5 render modes present this was destructive, having only 2 options available.
Since the render mode can now be changed on the fly this isn't as critical anymore as it once was.
With the software renderer not being used for 2D anymore it would be quite annoying if every texture class had to implement these.
If done properly, the SW renderer should actually be forced to dynamic_cast any texture to a FWorldTexture before using this stuff, but that'd be some pointless overhead better saved.

This removes the entire palette switch and all the special checks to ensure that no menu can be drawn over this image.
Instead it gives this texture its special palette in the texture manager so that the proper image is created right away.
I decided against exposing this as an editing feature because it is far too specific to this particular image and the raw page format it uses.
A quick check of /idgames shows no project ever replacing it - especially no ZDoom-based project - so no extended handling is needed to make this work with other texture formats.
- with renderers freely switchable, some shortcuts in the 3D floor code had to be removed, because now the hardware renderer can get FF_THISINSIDE-flagged 3D floors.
- changed handling of attenuated lights in the legacy renderer to be adjusted when being rendered instead of when being spawned. For the software renderer the light needs to retain its original values.
- 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
It may use the same calculations as the hardware renderer but must use the 2D drawer for display.
It should be investigated if the hardware renderer can do this as well.
This does not work with a setup where the same backend is driving both renderers.
Most of this is now routed through 'screen', and the decision between renderers has to be made inside the actual render functions.
The software renderer is still driven by a thin opaque interface to keep it mostly an isolated module.
