The input system backend was once used in the client and the renderers,
but for some years now it has been an integral part of the client only.
Move it there.
The last commits did some bigger changes to the interaction between the
GL renderers and the client. The code is now SDL 2.0 conformant, window
and context creation are strictly distinct operations. SDL is only
initialized when necessary. Since this broke the client <-> renderer
API, bump it's version.
There a lot of things left to do for dark and cold winter evenings:
* The software renderer implements it's own window handling and
reinitialized SDL whenever vid_restart is called. This is highly
problematic.
* vid_fullscreen is abused to communicate changes to renderer config
throughout the code. That's a very ugly, messy and potential very
problematic hack. But not easy to remove.
* Some funtion calls between the client and the renderer are
unnecessary.
The changes to the client <-> renderer interaction fixed issue #302.
* Sync both files as much as possible.
* Another round of general cleanup.
* Fix stencil tests.
* Simplify gamma handling, hardware gamma is now default.
* Support new client <-> renderer API.
* Another round of general cleanup.
* Introduce gl3_libgl cvar to force a libGL.
* Fix stencil buffer tests.
* Further untangle window <-> context stuff.
The window is now fully at client side, the context at renderer side.
This is another break of the renderer API. And at least GL1 needs to
track this, it's broken for now.
* Even more syntax and code style fixes.
* Rename functions to match their actual purpose.
* Fix comments.
* SDL initialization and shutdown is now client side only. With
SDL 1.2 finally gone there's no need to involve the renderers
in it.
This breaks the client <-> renderer API. I haven't bumped the API
version with this commit because there're likely more changes when
I'm going through the renderer side of things. The VID backend also
needs a lot of love...
It might be a good idea to move this SDL backend files into the client
and rename them. We'll decide that at a later time.
Until now, likely since we first introduced OGG/Vorbis playback 9 years
ago, in about 50% of all cases OGG_PlayTrack() was never called if
cd_shuffle was set 1, resulting in missing background music. Add the
missing call. :)
I wonder why I didn't catch this in sunday. For some reason a "make
clean ; make" cycle was necessary. Maybe a corner case that the header
dependencies didn't catch?
