0b35ceabdc GL3: added missing source files and stubs of most functions
still no 3D rendering, but in theory it should be able to load models,
bsps etc, just not render them yet.

also moved/copied md2.c and sp2.c to gl/ and gl3/ because they use
renderer-specific types

ebbb675cb8 GL3: gamma and intensity via shader
only for 2D rendering, as we don't have 3D yet; also this might need
a more flexible solution later, as some textures are not supposed to
have intensity applied.
According to the old R_Upload32*() and R_LightScaleTexture() the ones
without mipmaps didn't get intensity. Those were it_pic and it_sky (and
the ones in the "scrap", but those were it_pic too)

c098ee2ce3 LoadPCX() supports palette=NULL to avoid malloc()

aaa73236ec refexport_t::Init() now returns bool and has no args; minor things
the arguments were not used anyway, and returning true/false is clearer
than returning -1 (for error) or sth else (which has no deeper meaning
anyway).

Also:
* PrepareForWindow() can now return -1 if there's an error
* suppress some warnings in Makefile
* fix error for building ref_gl.dylib on OSX

5938a665e8 pass Com_VPrintf() to reflib used by R_Printf(), remove VID_Printf()
So in all code in the reflib (ref_gl.dll/.so/.dylib) calls to
ri.Con_Printf(print_level, fmt, ...) have been replaced by calls to
R_Printf(print_level, fmt, ...) which uses ri.Com_VPrintf().

a0c1c74a2e (Mostly) get rid of VID_Printf() and VID_Error()

54ae3be0c6 Com_VPrintf(level, fmt, argptr) (Com_D?Printf() wraps that)
somehow all the printf()-like things in Q2 wrap each other and each
one prints into a buffer and then calls the next one with ("%s", buf).
That's not very clever and kinda annoying.
As in the end everyone calls Com_Printf() I created Com_VPrintf()
that can be called instead with the va_list.

I also added printf-format annotation to Com_Printf() and Com_DPrintf()
and fixed places where Com_Printf() was called with the wrong type.

2b317075c7 Treat autoexec.cfg like every other config.
Until now autoexec.cfg was a special case. It was read several
times, whenever the 'game' cvar was altered or when the client was
restarted. But only if it was in the right directory in the right
position of the internal search path... Remove this altogether and
replace it by an ordinary 'exec autoexec.cfg' at startup.

This may break some mods that depend on an autoexec.cfg if the user has
his own version in ~/.yq2/. Such mods should use default.cfg instead.

This closes issue #163.

68a12d4ee1 Remove multitexturing support
Multitexturing was never part of any official Quake II release. It was
added in version 3.21, which was released only in source. Over the years
many developers tried to fix multitexturing, including myself. Yamagi
Quake II had it even enabled by default for several releases... But:

  * Multitexturing is poorly implemented and **slow**
  * Multitexturing leads to render errors, for example in city3
  * Multitextring is ortogonal to the normal render path and adds a
    lot of special cases to the renderer

Remove it for good. Ciao, it wasn't a nice time. :) The last version
before this commit was at least somewhat fixed, read some of the worst
problems were fixed. If someone's ever going to resurrect it, it would
be a good idea to start at that point.

f6f8394b74 Ensure that all keys are marked up when playing cinematics
Otherwise at least one key may be still marked as down causing an
immediate abort of playback. While here be a little bit paranoid
and clean up key states when focus is gained. In theory that's a
no-op.

f41f96e899 Use correct texture coordinates when drawing the video
When the video is scaled through OpenGL we can just throw it on our
vertexes and everything's alright. But when we're softscaling the video
we must consider that the videos size doesn't really match the vertex
size...

051be8285d Fix (text in) videos (for GPUs supporting NPOT textures)
especially in the intermission videos, the text looked broken, as parts
of the characters were missing.
This is because Draw_StretchRaw() converts the 320x240 video frame into
a 256x256 texture, without doing proper interpolation (just skipping
some pixels instead).
Now, if the GPU supports non-power-of-two texture sizes, the video
frames are uploaded as textures in their original size.

(Also fixed a harmless typo in common.h)

a0a34e0a35 When an invalid muzzle flash offset is send, just return.
The original client crashed (or survived by pure luck) when muzzle
flash offsets >210 were send. Our fix was to bail out, but that broke
some buggy mods... So just return and print an optional debug message.

This fixes issue #153.

7f996cc29e Don't smooth half height steps
This step height is used by several evelators, leading to stuttering due
to misspredictions. Additionally half height steps weren't smoothed by

1bbd8c04ff I think that steps between 94 and 98 are wrong, remove them.
Predicting these steps leads to a heavily stuttering elevator in
hangar1. I think that steps between 94 and 98 can't appear on stairs, so
just remove them. If I'm wrong we need a hack to the hack ontop of the
hack... ^^

9af1af55a5 Allow reading player models from pak / pk2 / pk3 / zip files.
This fixes #119. As always I've chosen the least invasive way to solve
this problem. Trying to open players/$model/trix.md2 is hack, but solves
the problem without changes to filesystem.c and it's API.

4d9d555d8e When vsync is enabled, cap the desired rfps.
With vsync enabled the render times of consecutive frames can diverge.
The first frame arrives right at the next display frame and is rendered
without waiting time. The next frame has to wait 20ms. The leads to some
problems with the move prediction if the client is asynchronous. Fix
this by capping the desired frame rate at the display refresh rate. Also
make sure that the network framerate is never higher then the renderer
framerate.

With the commit the timing is always correct:
* With no limit as much frames as possible are rendered. In this case
  rfps > nfps and everything's good.
* With vsync enabled rfps > nfps or rfps == nfps is given. Also rfps
  will never exceed the display refresh rate.
* On slow hardware either rfps > nfps or an implicit rfpc == nfps is
  given.

93e9633382 Port step smoothing code from r1q2.
While the bugfix in a6f4a3b made the steping prediction working for

d6136cbba5 Bump cl_maxfps to 60.
Yesterday I chose setting cl_async to 0 since I saw some movement
changed with the async client enabled. Especially when clipping against
bevels the game started to stutter and there were small rendering
problems. After some debugging I realized that it is caused by slight
inaccuracies in the move prediction. When cl_maxfps is too low, the
movement error between two render frames becomes to big, leading to
misspositions. There're two ways to solve this problem:

* Processing more client frames. Most async clients I've looked on
  process 60 or even 90 render frames. I chose to stay at 60 since
  I was unable to see differences with higher rates.

* Changed to pmove.c and the pmove_t struct. Some multiplayer focused
  clients go that way. But there's a very high of breaking singleplayer
  movement and pmove_t is part of the server <-> game API. Additionally
  the network code must / should be altered. So this is unsuitable for
  YQ2.

Please note that there's still a change in movement. Before 4ae8706 and
when cl_async is set to 0 movement is dependend on the render framerate.
At low framerate bevel clipping isn't working too good, at high
framerates prediction causes physics changes like the famous 125hz bug.
With cl_async set to 1 the network framerate is stable, leading to a
more consistant behahiour.

070d94ec77 Add a cvar cl_async, off by default.
Most (all?) clients implement the synchronous and the asynchronous
client by seperate code pathes. Instead of doing that we force the
asynchronous path to process one network frame for each render frame.

a6f4a3b309 Don't predict one frame too far.
We're missusing the current frame to pass data from the input subsystem
to the movement prediction without a server frame. While we can use the
current frame for the movements itself, it's not finished and thus
unsuitable for stair step prediction. Also oldframe is determined
wrongly. As a result the player "jumps" over stairs.
