ea223f6312 [sw] Clean up use of r_rectdesc
I have no idea why the struct even had a local vrect that was used for
temporary storage.

ea2fd32228 [renderer] Merge screenshot code as much as possible
Only CaptureBGR is per-renderer as the rest of the screenshot code uses
it to do the actual capture (which is target dependent). Vulkan is
currently broken due to capture being an asynchronous process and the
rest of the code expecting capture to be synchronous (also, bgr vs rgb).

The best thing is all renderers now write the same format (currently
png).

2a87983bf4 [sw] Remove some unnecessary casting
I'm not sure what the author of that code was thinking (maybe trying to
do 4 pixels at a time?), but the resulting code still did only one.
Better to remove all the casts, use the right pointer type, and keep the
code clear.

5eb397dd31 [renderer] Remove more dead code
The back-buffer and video buffer locking code was pretty much never more
than stubs (except maybe in dos quake).

9514ad1ae4 [gl] Draw sky chains before brush entities
Drawing sky chains first ensures that sky surfaces correctly block parts
of the map that should not be visible (by writing the correct depth to
the depth buffer when doing box or dome skies). Writing brush models
first means that the models (ammo boxes etc) could be visible when they
should not be.

73444c3b7a [ruamoko] Give the scene resource block a rua prefix
No effect on the code itself, but it makes debugging much easier when
there aren't two very different structs with the same name.

d69355f521 [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.

6ec8e29429 [scene] Track hierarchies instead of root transforms
The root transform of each hierarchy can be extracted from the first
transform of the list in the hierarchy, so no information is lost. The
main reason for the change is I discovered (obvious in hindsight) that
deleting root transforms was O(n) due to keeping them in an array, thus
the use of a linked list (I don't expect a hierarchy to be in more than
one such list), and I didn't want the transforms to be in a linked list.

7906db5a37 [client] Set camera rotation for chase mode 1
With the change in cl_view separating chase cam updates from
first-person updates, the auto-rotation of the camera was lost.

f296cb897e [renderer] Make draw order a little more consistent
GL and GLSL were drawing the view model after particles instead of
before. For GL, this is likely due to avoiding fog affecting the view
model (which I think is not the right thing to do), and GLSL due to
copying GL (because I had no idea at the time). This makes the two
renderers consistent with the software renderers, and might even speed
things up a little as that's one less set of blends to do when the
particles are covered by the view model (I don't expect much
difference).

ae6970a005 [renderer] Split entity queue into per-model-type
While I doubt the difference is all that significant, this should speed
up entity rendering because it cuts out a lot of branching, and
eliminates scanning the same list multiple times only to not do anything
for large chunks of the list.

ab91d73635 [scene] Use scene resources for the main hierarchy block

b210f01837 [scene] Manage scene roots in transform
Since transforms now know the scene to which they belong, and they know
when they are root and when not, getting the transform code to manage
the scene roots is the best way to keep the list of root transforms
consistent.

54c3b4cc53 [client] Get the chase camera working with input
It turns out cam_controls is for pointing the player model in the
direction of movement rather than controlling the camera (I should add
proper camera controls).

7c07118541 [mathlib] Clean up AngleVectors comment
I finally spent the time to work out what it was trying to say. Still
not sure it's clear, but what is clear is that there was probably some
disagreement at Id about the orientation of the world.

1859ff233d [client] Fix the chase cameras
They no longer spin like crazy. I don't know how, but I must have broken
something over the years as I'm sure Seth had the code working (and I
seem to remember seeing it working). In the process, clean up a lot of
the angle mess.

5b08ee768c [client] Clean up chase camera code
It's a lot easier to read (and see the difference between modes 2 and 3)
with all the ifs removed, and the state is properly is chasestate_t now
(though not handled properly on level reset etc).

43a329dcb5 [client] Get the basic chase camera working
The more advanced modes are rather broken (continuous spinning), but
they may have been for a while. The bulk of the various changes were due
to renaming viewstate's origin and angles to make their meaning more
explicit.

2477a44d15 [client] Move cshift info from viddef to viewstate

7d059a0b56 [client] Merge nq and qw cl_view
They've been near-identical for years, now they're only one. It proved
necessary to start merging the HUD code which for now is just a few cvar
declarations (not even init), but that should be a separate set of
commits.

e920abe142 [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.

deff95f490 [client] Merge chase camera and much of input
Handling of view angles is a little hacky at the moment, but this gets
the chase camera code and most of the common input code into one place,
which will make cleaning up the camera code much easier.

e67ec84db9 [vulkan] Use simpler projection and z_up matrices
While both matrices had positive determinants in the first place, I find
the projection matrix easier to understand without all the negatives,
and having quake-x/vulkan-z positively parallel in the z-up matrix makes
that a lot easier to think about.

cd26073b6a [vulkan] Update the sky matrix
Regardless of whether the sky is spinning or not, the matrix needs to be
updated with the current origin in order to get the direction vector
right in the shader. Also, it's in the update that the required x-y
plane rotation gets in so the skies move in the correct direction.
