In the old times the refresher was a stand alone DLL. For performance
reasons and to avoid laggy input parts of the input system were
implemented in this DLL. Now that the renfresher is part of the main
binary and initialized at client startup we can remove most of the
abstractions between input system, refresher and client. Also the
input system can be treated as a normal subsystem.
Changes:
- Untangle the VID_* stuff and the IN_* stuff. The functions
called by function pointers in in_state are now called directly
and 'struct in_state' was removed.
- Remove input.h and rename the appropriate backend functions.
There's no longer a need for an abstraction layer between the
input backend and the input frontend.
- Move input initialization and shutdown into CL_Init(), like it's
already done for all other subsystems.
- Remove Key_ClearStates(). I'm pretty sure that's a left over from
the old Win 9x backends and unnecessary.
- General cleanup.
This function is only used in cl_view.c, so no need for external
declaration. Reimplement it in a sane and on all platform 64 bit
clean way. This allows us to finally remove the horible INT macro.
For ia64 it's necessary to define int as long long instead of long int. I know
this for a fact because pointers that were encoded as long int in my LLVM and
CLIPS bridge would fail horribly when passed out of clips back into LLVM. long
long fixed it.
If "horplus" is set, the "fov" cvar is interpreted as the horizontal FOV
in a 4:3 screen, and is adapted automatically to the current screen
aspect ratio accordingly. If not set, use the old Vert- approach.
In addition, "horplus" can also be set from the video menu by selecting
the "Auto" option for aspect ratio, which also resets the FOV value to the
standard 90 degrees.
Finally, add a 5:4 aspect ratio (1280x1024) and correct the 16:9 angle
slightly.
