[renderer] Support multiple entity queues While there's currently only the one still, this will allow the entities to be multiply queued for multi-pass rendering (eg, shadows). As the avoidance of putting an entity in the same queue more than once relies on the entity id, all entities now come from the scene (which is stored in cl_world in the client code for nq and qw), thus the extensive changes in the clients.

[glsl] Implement fisheye rendering The code dealing with state is a bit of a mess, but everything is working nicely. Get around 400fps when all 6 faces need to be rendered (no surprise: it should be about 1/6 of that for normal rendering). The messy state handling code did not come as a surprise as I suspected there were various mistakes in my scene rendering "recipe", and fisheye highlighted them nicely (I'm sure getting this stuff working in Vulkan will highlight even more issues).

[renderer] Clean up entity_t to a certain extent This is the first step towards component-based entities. There's still some transform-related stuff in the struct that needs to be moved, but it's all entirely client related (rather than renderer) and will probably go into a "client" component. Also, the current components are directly included structs rather than references as I didn't want to deal with the object management at this stage. As part of the process (because transforms use simd) this also starts the process of moving QF to using simd for vectors and matrices. There's now a mess of simd and sisd code mixed together, but it works surprisingly well together.

[glsl] Adjust view/projection matrices for consistency The actual view and projection matrices are now consistent with vulkan, with the vulkan-gl disparity moved into adjustment matrices. The goal is to allow the same camera data and code to be used in all renderers. The extra matrix multiplication shouldn't be too expensive as it occurs only when the field of view (not often, under user control) or near and far clip distances (very rarely) change.

[renderer] Clean up use of vup/vright/vpn This moves the common camera setup code out of the individual drivers, and completely removes vup/vright/vpn from the non-software renderers. This has highlighted the craziness around AngleVectors with it putting +X forward, -Y right and +Z up. The main issue with this is it requires a 90 degree pre-rotation about the Z axis to get the camera pointing in the right direction, and that's for the native sw renderer (vulkan needs a 90 degree pre-rotation about X, and gl and glsl need to invert an axis, too), though at least it's just a matrix swizzle and vector negation. However, it does mean the camera matrices can't be used directly. Also rename vpn to vfwd (still abbreviated, but fwd is much clearer in meaning (to me, at least) than pn (plane normal, I guess, but which way?)).

[cvar] Make cvars properly typed This is an extremely extensive patch as it hits every cvar, and every usage of the cvars. Cvars no longer store the value they control, instead, they use a cexpr value object to reference the value and specify the value's type (currently, a null type is used for strings). Non-string cvars are passed through cexpr, allowing expressions in the cvars' settings. Also, cvars have returned to an enhanced version of the original (id quake) registration scheme. As a minor benefit, relevant code having direct access to the cvar-controlled variables is probably a slight optimization as it removed a pointer dereference, and the variables can be located for data locality. The static cvar descriptors are made private as an additional safety layer, though there's nothing stopping external modification via Cvar_FindVar (which is needed for adding listeners). While not used yet (partly due to working out the design), cvars can have a validation function. Registering a cvar allows a primary listener (and its data) to be specified: it will always be called first when the cvar is modified. The combination of proper listeners and direct access to the controlled variable greatly simplifies the more complex cvar interactions as much less null checking is required, and there's no need for one cvar's callback to call another's. nq-x11 is known to work at least well enough for the demos. More testing will come.

[renderer] Make R_RenderView private This is actually a better solution to the renderer directly accessing client code than provided by 7e078c7f9c8ab27af92ff268f49bac070c9ff617. Essentially, V_RenderView should not have been calling R_RenderView, and CL_UpdateScreen should have been calling V_RenderView directly. The issue was that the renderers expected the world entity model to be valid at all times. Now, R_RenderView checks the world entity model's validity and immediately bails if it is not, and R_ClearState (which is called whenever the client disconnects and thus no longer has a world to render) clears the world entity model. Thus R_RenderView can (and is) now called unconditionally from within the renderer, simplifying renderer-specific variants.

I imagine things are a bit of a mess with view size changes, and especially screen size changes (not supported yet anyway), and vulkan winds up updating its projection matrices every frame, but everything that's expected to work does (vulkan errors out for fisheye or warp due to frame buffer creation not being supported yet).

Separate render module loading from initialization. This allows the vid module to load the render module and access render specific functions before the renderer initializes, which happens to need an initialized vid module...

Fix the calls for Draw_Init in the gl renderers. While namehack.h took care of the symbol mangling, I do prefer the calls to be correct as it reduces confusion.

Make the init process more dependency based. Most subsystems that depend on other subsystems now call the init functions themselves. This makes for much cleaner client initialization (more work needs to be done for the server).

[glsl] Implement fisheye rendering The code dealing with state is a bit of a mess, but everything is working nicely. Get around 400fps when all 6 faces need to be rendered (no surprise: it should be about 1/6 of that for normal rendering). The messy state handling code did not come as a surprise as I suspected there were various mistakes in my scene rendering "recipe", and fisheye highlighted them nicely (I'm sure getting this stuff working in Vulkan will highlight even more issues).

[glsl] Implement screen warp when in liquids Finally, after a decade :P Looks pretty good, too, and is (almost) properly scaled to the resolution (almost because the effect is a little squashed, but I think the sw renderer does the same).

Get glsl running as a null renderer. This means that nq-glslx can get through demo1, demo2, demo3 and bigass1 without crashing. However, nothing is rendered, so unless you like black, it's not very interesting.

Fix the missing world on map reload. If the map got reloaded but the current leaf didn't change the world (and most entities) didn't get drawn. Forcing a vis update by first setting r_viewleaf to null and marking surfaces does the trick :)

// Force a vis update
[model] Move visframe out of msurface_t One more step towards BSP thread-safety. This one brought with it a very noticeable speed boost (ie, not lost in the noise) thanks to the face visframes being in tightly packed groups instead of 128 bytes apart, though the sw render's boost is lost in the noise (but it's very fill-rate limited).

[particles] Merge particle spawning into client After yesterday's crazy marathon editing all the particles files, and starting to do another big change to them today, I realized that I really do need to merge them down. All the actual spawning is now in the client library (though particle insertion will need to be moved). GLSL particle rendering is semi-broken in that it now does only points (until I come up with a way to select between points and quads (probably a context object, which I need anyway for Vulkan)).
