c7ebe82131 Calculate bounds for unanimated IQM models
Bounds are optional for animated IQM models but are not possible to
include with unanimated models (seems intended for use with separate
model containing animations and bounds). Calculating bounds for
unanimated IQM models fixes culling and head model on HUD which
calculates position from model bounds.

1994801e1c Fix axis returned by IQM's LerpTag
The axis returned for IQM tag was the animation's joint rotation without
the base frame joint rotation. It only worked correct for models that
did not rotate the base frame joints.

11337c9fa2 OpenGL2: Add GPU vertex skinning for IQM models
Using GPU vertex skinning is significantly faster than CPU vertex
skinning. Especially since OpenGL2 has to run R_VaoPackNormal() and
R_VaoPackTangent() each vertex each frame which causes CPU vertex
skinning to be significantly slower than OpenGL1 renderer.

cccd283be8 Improve IQM CPU vertex skinning performance
Only calculate vertex blend matrix for each unique bone indexes/weights
combination once per-surface instead of recalculating for each vertex.
For best performance the model surfaces needs to use few vertex bone
indexes and weights combinations.

Unroll loops so GCC better optimizes them.

In my tests drawing animated IQM may take 50% as long in opengl1 and
70% as long in opengl2. It will vary by model though and might not
help much at all.

Made unanimated IQM models skip matrix math altogether.

fdc08e860e Improve IQM loading
- Only allocate memory for vertex arrays that are present in the IQM
file and are actually used (may not have colors or blend index/weights,
don't load tangents in opengl1). (Colors is fixed to next commit.)
- Explicitly handle loading IQM files without meshes (bones only).
- Better IQM validation. Header data offset 0 mean data is not present
in file. Check if required vertex arrays are present.

This involved a lot of white space changes and moving code around.

6c3d92133d Fix IQM root joint backlerp when joint number is more than 0
Backlerp for root joint (joint with no parent) was always applied to
joint 0. This is an issue when a model has multiple root joints.

39e2113c73 OpenGL2: Misc fixes and cleanup
Fix two constants in GLSL shaders. Remove f suffix from float and fix
int to float assignment. They were causing shader compile errors in
OpenGL ES 2 context.

Remove disabling clip plane. Clip plane is unused and never enabled in
the opengl2 renderer. Remove disabling it to avoid causing a GL error
when using OpenGL 3.2 core profile or OpenGL ES.

Make VAO cache vertex stride be size of srfVert_t since that is what
is uploaded to the GPU. No behavior change. There is a disabled debug
id in srfVert_t though which if enabled changes srfVert_t size.

14cc4cc6cb OpenGL2: Fix world VAO cache drawing when glIndex_t is unsigned short
OpenGL ES is only required to support unsigned short for element buffer
values.

R_DrawElements() firstIndex argument was glIndex_t which caused element
indexes to wrap around to 0 when glIndex_t is an unsigned short.
(glIndex_t is an index into the vertexes buffer, not element buffer.)
Change it to 'int' like tess.firstIndex which is passed to
R_DrawElements().

World VAO cache buffer size allowed storing more vertexes than unsigned
short glIndex_t could reference. This resulted in the vertex indexes in
the element buffer wrapping around to 0.

74ec00ddaf OpenGL2: Fix holodeck doors being black and not fading out
On Windows the opaque textures on the holodeck doors model were drawn
solid black and did not fade out.

Set up ref entity lightDir and modelLightDir as unit vectors. I am
guessing the vector lengths are being used as a divisor in a GLSL shader
or something.

Also clear directedLight so the same fields are set for RF_FULLBRIGHT as
all other ref entities.

4fa93fbfd4 Fix client kicked as unpure when missing the latest cgame/ui pk3s
In 2013 ioquake3 stopped referencing the pk3 file that qagame.qvm was
loaded from. This had the unintended side affect of causing
non-dedicated pure servers to no longer reference a pk3 that only
contains the three QVM files.

Non-dedicated pure servers did not reference the pk3 containing the
latest cgame.qvm so if client did not have the pk3 file they were kicked
as unpure instead of the client trying to download the pk3 file.

Also make server touch ui.qvm since it's required to pass pure check and
may be separate from cgame.qvm.

58f257e868 Send empty snapshots to clients downloading using legacy protocol
Save bandwidth by excluding entity and player state changes from
snapshots sent to clients downloading using the legacy protocol. The
snapshots are mainly needed to update the reliableAcknowledge.

The idea is from Noah "Chomenor" Metzger's ioef-cmod project. Though I
implemented the dummy snapshot code closer to the real snapshot code.

5909b9a1cf Isolate the Altivec code so non-Altivec PPC targets can use the same binary.
Moved all the code using Altivec intrinsics to separate files. This 
means we can optionally use GCC's -maltivec on just these files, which
are chosen at runtime if the CPU supports Altivec, and compile the rest
without it, making a single binary that has Altivec optimizations but
can still work on G3.

Unlike SSE and similar extensions on x86, there does not seem to be
a way to enable conditional, targeted use of Altivec based on runtime
detection (which is what ioquake3 wants to do) without also giving the
compiler permission to use Altivec in code generation; so to not crash
on CPUs that do not implement Altivec, we'll have to turn it off
altogether, except in translation units that are only entered when
runtime Altivec detection is successful.

This has been tested on Linux PPC (on an Altivec-enabled CPU),
but we may need further work after testing trickles out to other
PowerPC devices and ancient Mac OS X builds.

I did a little work on this patch, but the majority of the effort belongs 
to Simon McVittie (thanks!).

2326a060b9 Don't allow SDL audio capture using pulseaudio
When you start recording using SDL pulseaudio driver the client sends
all audio captured while not recording. 240 milliseconds of audio is
sent each frame until the capture buffer is empty. This is a problem for
privacy and causes confusing to debug VoIP playback issues on other
clients connected to server and when playing back demos.

10abac8fa0 Fix duplicate bots displayed in Team Arena ingame add bot menu
The key handler allowed going 2 beyond the end of the bot list and the
display function clamped to 0 causing the first bot to be shown 3 times.

Attempting to add the bot in gametypes < GT_TEAM would fallback to
Sarge in UI_GetBotNameByNumber() (who isn't the first bot) and gametypes
>= GT_TEAM would access characterList past known values (typically NULL
but if teaminfo.txt contained 63 characters it would access out of
bounds memory).

51743bbb01 Improvements for dedicated camera followers (team follow1/2)
Switching to dedicated camera follower with no possible players to
follow would spawn at the intermission point and display "connection
interrupted" HUD message. Pmove() was not run for the client so
ps.commandTime was too far behind. I made it so that dedicated camera
followers and scoreboard run Pmove() but cannot move (PM_FREEZE).

When all players possible to follow leave, the dedicated camera follower
would continue to display the old player state of the player they were
following (along with "connection interrupted" HUD message). Unlike the
regular case of a spectator following a specific player, dedicated
camera followers did not reset their player state to the intermission
point after the followed player was no longer valid.

Now a client can be set as 'team follow1' to automatically switch
between displaying the intermission point and following a player when
possible.

9a0ee67e04 Make macOS Universal Bundle target 10.6 for x86 and x86_64
SDL 2.0.5 dropped support for macOS 10.5 so target 10.6 instead. The
PPC build uses SDL 2.0.1 so it still targets 10.5. macOS 10.5 (x86,
x86_64) should automatically run the PPC build using Rosetta.

Revert MAN-AT-ARMS' change to SDL 2.0.8 SDL_platform.h that allowed
targeting macOS 10.5 for the sake of PPC. It also incorrectly allowed
x86 and x86_64 to target 10.5 as well. (Also macOS PPC uses separate
headers now.)

allow compiling using macOS 10.5 SDK. Using separate headers allows the
engine to check the SDL version for enabling newer SDL features.

device, etc, that the OpenAL codepath does.
