- added a software scene drawer to the GL renderer.
...
It still looks like shit and only works on the modern render path but at least the basics are working.

- starting separation of hardware dependent and hardware independent code, starting with aabbtree, because it was easy.

- moved all variables not related to the hardware renderer's texture state out of gl_info.

- moved the code in gl_data.cpp to better fitting places
...
* 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

- moved CreateTexBuffer out of the GL code.
...
This is merely a buffer creation function with no dependencies on the renderer.

- implemented desaturation for the legacy GL renderer's 2D.
...
A lot of work that's only needed to be able to use the hardware renderer's 2D code with the software renderer.

- 2D drawer implementation complete for hardware renderer.
...
This also replaces DTA_ColormapStyle with proper implementations of its components. As implemented it was a very awkward mixture of various effects that already existed in a separate form. As a result of its implementation it required additional but completely redundant shader support which could be removed now. As a side effect of this change a new DTA_Desaturate option was added.

- fixed alpha texture generation for OpenGL rendering.
...
The old logic used a translation table that does not work with color images, it was designed to handle 8 bit grayscale images.
So now, it creates a true color buffer and then turns it into a texture with R,G,B = 255 and the alpha channel set to the grayscale value.
This was also the reason why crosshairs made from 32 bit PNGs did not show correctly.

- adjusted GL renderer to the new rules for alpha textures. This means that the translation fallback is only needed for the legacy renderer now. Modern GL can use the regular texture and will apply a grayscale mapping instead of merely using the red channel.

- fixed: Camera textures must always be drawn with texture mode opaque, because the contents of their alpha channels are undefined.

- moved the matrix code out of 'gl' because the model code also needs it.

- use normals to have proper light attenuation. So far only implemented for walls and flats. Models are planned but need some thinking about how to efficiently collect all required lights for an object.

Add gbuffer pass support to FShaderManager and FRenderState

Christoph Oelckers
8b6e09ca09
- changed the license of the OpenGL renderer to LGPL v3.
...
This was done to clean up the license and to ensure that any commercial fork of the engine has to obey the far stricter requirements concerning source distribution. The old license was compatible with GPLv2 whereas combining GPLv2 and LGPLv3 force a license upgrade to GPLv3. The license of code that originates from ZDoomGL has not been changed.

- on older ATI drivers where the clip planes are broken, only disable the clip planes themselves, but not OpenGL 3.x so that dynamic lights still work as intended.
...
- only disable clip planes on Windows, but not on Linux or macOS.
- If a driver reports full OpenGL 4.5 support, assume that all features are working properly.

- cleaned up the clip plane management for portals.
...
Unfortunately the math behind the old clip planes is utterly impenetrable and so poorly documented that I have no idea how to set that up, so it is deactivated for now. It wasn't working anyway.

- added workarounds for the invulnerability colormap for non-shader rendering. Unlike the shader based versions these do not decolorize the screen. The advantage to the old texture duplication is that this is far less stressful on performance.

- fixed: The depth clamp setting needs to be tracked per portal so that it can be properly restored afterward.
...
Regular skies need it off but SkyViewpoints need it on - and all others need to use the parent's setting.
So without engine side tracking we can end up rendering the sky with this setting off, resulting in omission of the fog layer.

- changed the handling of alpha textures. The only special case they need is with palette-less textures and this can be handled far more easily and robustly with a predefined translation instead of passing another parameter through all the layers of the texture management code. This also fixes problems with paletted PNGs that get used as an alpha texture because the old method clobbered the image's palette.

- reactivate compatibility profile so that immediate mode drawing can be used on older hardware not supporting persistently mapped buffers.
...
- reactivate alpha testing per fixed function pipeline
- use the 'modern' way to define clip planes (GL_CLIP_DISTANCE). This is far more portable than the old glClipPlane method and a lot more robust than checking this in the fragment shader.
