* 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.
this happens when you just copypaste and adapt r_lefthand
also did some minor changes to R_AliasDrawModel in the soft renderer
to make sure alias[xy]scale is reset properly in the early out cases
At high 'fov' values the weapon looked quite distorted.
Now it's rendered with an independent FOV, which looks better.
Note that the 'fov' cvar sets fov_x, while this is based on fov_y
(which is calculated from fov_x), so it's indeed different values:
r_gunfov seems to correspond to fov 90.
We use r_gunfov 80 as default, because it looks better.
Loop 'for ( i = 0; i < 3; i++ )' sets values to vtx[0..2]. So next index must be 3(instead 4) and
loop 'for ( i = 16; i >= 0; i-- )' will set vtx[3..(18*3-1)].
