* r_mode defaults to 5 (1024x768), I think that's more sane than 640x480
* r_fullscreen defaults to 0 (=> windowed mode) because fullscreen in
the wrong resolution sucks.. let people do their initial configuration
in windowed mode
* r_swapInterval defaults to 1 (=> VSync active by default) because that
makes the game feel more smooth and most PCs should be able to 60fps
in this 11years old game anyway
* s_useEAXReverb defaults to 1 (=> use EAX/EFX effects by default),
because OpenAL-soft supports them on all platforms/hardware and if
for some reason the used OpenAL implementation doesn't support it,
it's deactivated automatically anyway.
All these things can be configured in the Options Menu.
First attempt at porting the EAX reverb code to EFX.
This only works when the ALC_EXT_EFX extension is supported by
the OpenAL vendor (which is not the case for the OSX supplied
framework, use OpenAL soft instead).
The current stable version of OpenAL Soft (v1.13 as of this
writing) can barely handle this additional workload, current
master is highly recommended when using this feature.
We already link to OPENAL_LIBRARY further down.
Log some debug OpenAL info, mainly so OSX users can check they are not
using Apple's OpenAL. OpenAL Soft is recommended as it fixes many
issues.
I specify it as follows:
cmake -DOPENAL_LIBRARY=/usr/local/lib/libopenal.dylib -DOPENAL_INCLUDE_DIR=/usr/local/include -GXcode ../neo/
(because FindOpenAL.cmake prefers the /System frameworks)
Don't include the lazy precompiled.h everywhere, only what's
required for the compilation unit.
platform.h needs to be included instead to provide all essential
defines and types.
All includes use the relative path to the neo or the game
specific root.
Move all idlib related includes from idlib/Lib.h to precompiled.h.
precompiled.h still exists for the MFC stuff in tools/.
Add some missing header guards.
Use the CVar s_numberOfSpeakers for that, its already stored
in there.
Add the same (!= 2 && !=6) check as in the audio backends since
the mixer is limited to these 2 values.
