This is changing more then I wanted to at once, however. The major change is that we no longer require libGL to even exist on the system at compile time for the GL targets, we dynamicly link to the libGL of choice at run time. (This probably breaks most non-linux systems, and all GL targets except -glx, some fixup will be needed.) (This also kills glquake, dead dead DEAD! GONE FOREVER! WHEE!) Some gl_draw cleanup. Commented out equake alias model occlusion test stuff, very experimental. Added the .lo and .la patterns to the .gitignore files. Some minor sbar cleanup. (We don't use the disc in use symbol for anything.)

[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] 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.

Apply colormod as glColor, rather than adding it to emission, to prevent QSG2 issues with fullbrights. Rearrange init code, and don't go quite as wild with responsiveness to lights.

[model] Move plane info into mnode_t, and visframe out The main goal was to get visframe out of mnode_t to make it thread-safe (each thread can have its own visframe array), but moving the plane info into mnode_t made for better data access patters when traversing the bsp tree as the plane is right there with the child indices. Nicely, the size of mnode_t is the same as before (64 bytes due to alignment), with 4 bytes wasted. Performance-wise, there seems to be very little difference. Maybe slightly slower. The unfortunate thing about the change is the plane distance is negated, possibly leading to some confusion, particularly since the box and sphere culling functions were affected. However, this is so point-plane distance calculations can be done with a single 4d dot product.

[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.

Fix some (ancient) apparent bugs in GetAliasFrameVerts16(). Clamp minlight, instead of adding it. Apply colormod as glColor, rather than adding it to emission, to prevent QSG2 issues with fullbrights. Rearrange init code, and don't go quite as wild with responsiveness to lights. Material & lightmode settings will need tweaking & testing to work well on all cards. Feedback needed there.

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).

[gl] Make perspective matrix setup consistent Now GL perspective matrix setup matches that of GLSL and Vulkan, and GL's z_up matrix matches GLSL's (as it should, since they're really going through the same API). GL also needs the depth adjustmet matrix now. Other than having to google the docs for glFrustum, there's nothing wrong with the function itself, but it's nice to have direct control over the matrices. In the process, I discovered how horribly confused I've been at times with respect to the handedness of GL and Quake: GL is right-handed (y-up, z-out, x-right), as is Quake itself (but z-up, y-left, x-in), but as the perspective matrix used in the three renderers expects z-in, having x-right and y-up makes the matrix effectively left-handed (not for Vulkan though, because there it's y-down, x-right, z-up, so right-handed again).

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?)).

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] 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.

[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.

[gl] Get fisheye working with frame buffers Of course, it's not as correct as glsl or sw due to using polygons and uvs rather than a fragment shader (not that such is out of the question since GL 3.0 is requested, but I don't feel like getting shaders going just for a couple of post-processing effects in an obsolete renderer).

[renderer] Get fisheye working again Only for gl and sw at the moment (want to merge things further before I do anything for glsl or vulkan). However, with with I've learned getting gl and sw to work, glsl and vulkan will be trivial.

[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)).
