c05a15dec5 [glsl] Use vec4f_t in a few more places
No idea if it makes a noticeable speed difference, but it makes a huge
readability difference.

62cce7f98c [gl] Remove some more warts
seeing ptexels and pixels together is very confusing

169e0192f2 [gl] Use the correct value for sqrt(0.5)
707106781 looks right, but isn't quite.

693225a16f [util] Add a fixme for a comment
The code itself is fine, but the comment is rubbish because it's
confusing, though essentially correct.

098ceed5ff [client] Merge nq and qw temp entity handling
This finally gets cl_tent merged away.

fbc1bd9f6e [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.

3230270ae3 [entity] Start work on a new entity library
The plan is to have a fully component based entity system. This adds
hierarchical transforms. Not particularly useful for quake itself at
this stage, but it will allow for much more flexibility later on,
especially when QuakeForge becomes more general-purpose.

14bc560624 [build] Add option to enable gcov data generation
Nice to be able to check how good the tests are (or aren't, as the case
may be).

4a97bc3ba5 [util] Create simd quaternion to matrix function
This seems to be pretty close to as fast as it gets (might be able to do
better with some shuffles of the negation constants instead of loading
separate constants).

0366b72d4a [vulkan] remove the fps printing
Now that pixels are rendered, there's no need to print the fps
separately as the in-game display works quite nicely.

4d8ce22c17 [vulkan] Load the map's lights into an array
It's not used yet as work needs to be done to better support generic
entities, but this is the next step to real-time lighting (though, to be
honest, I expect it will be too slow to be usable).

e3762d8f38 [util] Make plist mostly null-safe
The main purpose is to allow fluent-style:
    const char *targetname = PL_String (PL_ObjectForKey (entity, "targetname"));
    if (targetname && !PL_ObjectForKey (targets, targetname)) {
        PL_D_AddObject (targets, targetname, entity);
    }

[note: the above is iffy due to ownership of entity, but the code from
which the above comes works around the issue]

eb0aa2dcea [renderer] Clean up most globals in efrags
There's still the memory management itself to clean up, but the main
code no longer uses any static/global variables (holdover from when the
function was recursive rather).

9617bbef97 [build] Create static libs for render targets
The static libs are used to build the plugins, but make it easy to use
only those modules needed for tests. Fixes the link error when running
"make check" with non-static plugins.

fd97bb1456 [vulkan] Implement linear falloff
It's possibly too bright, but it might be the lights themselves. Still,
it looks better than the no-falloff implementation.

33575f93d5 [vulkan] Implement deferred lighting for dlights
Static lights are yet to come (so the screen is black most of the time),
but dynamic lights work very nicely (and look very good) despite the
falloff being incorrect.

918c3af095 [vulkan] Add a position buffer to the g-buffer
While I could reconstruct the position from the screen coords and depth,
this is easier and good enough for now. Reconstruction is an
optimization thing.

10a1b99a92 [vulkan] Implement lighting and compose passes
Lighting doesn't actually do lights yet, but it's producing pixels.
Translucent seems to be working (2d draw uses it), and compose seems to
be working.

e6ecf5e855 [vulkan] Fix up commands for deferred rendering
Nothing gets output yet (lighting and composite passes not implemented),
but everything passes validation until exit (not destroying everything).

4245c6ad3b [vulkan] Specify subpass number in pipeline def
This gets the alias model render pass and pipeline passing validation.

I don't know why I didn't add the subpass field to the
VkGraphicsPipelineCreateInfo parser def, though it could be I simply
missed it, or I thought I wouldn't need it at the time.

64740b0f73 [vulkan] Create shaders for alias deferred rendering
A simple (no uv output) vertex shader that still blends the two frames,
and the relevant g-buffer fragment shader.

b08c3881b9 [vulkan] Add a comment about using size_t
Due to wanting to access array sizes when parsing uint32_t type values,
parse_uint32_t needs to handle size_t values even though it throws out
any excess bits.

4bda49d798 [util] Correct the lex priority for int constants
The actual need to specify unsigned int constant is a bit of a pain, but
not being able to do so due to lex priority errors is even more of a
pain.

a94949c009 [vulkan] Start moving towards a deferred renderer
After getting lights even vaguely working for alias models, I realized
that it just wasn't going to be feasible to do nice lighting with
forward rendering. This gets the bulk of the work done for deferred
rendering, but still need to sort out the shaders before any real
testing can be done.

55104ac430 [util] Allow "any type" results for cexpr
Setting the result type cexpr_exprval tells cexpr to simply return whoe
exprval object rather than the referenced value, thus allowing the
caller to check the type when the expression is context sensitive.

5535d1f8e6 [util] Keep track of plist dictionary key order
The order in which keys are added to the dictionary object is
maintained. Adding a key after removing an old key adds the new key to
the end of the list rather than reusing the old key's spot.

0dcd946063 [util] Add plist parser for dictionary -> array
PL_ParseLabeledArray works the same way as PL_ParseArray, but instead
takes a dictionary object. The keys of the items are ignored, and the
order is not preserved (at this stage), but this is a cleaner solution
to getting an array of objects when the definitions of those objects
need to be accessible by name as well.
