This can be used to improve automap readability on high-resolution
displays.
Some automap options in the menu were reordered to follow a more
logical order.
* Added SBSLETTERBOX to menudef.txt
* Changed PresentSideBySide in gl_renderer
Needed for new side-by-side mode
* Added VR_SIDEBYSIDELETTERBOX to gl_stereo3d.cpp
For side by side letterbox display mode
* Added VR_SIDEBYSIDELETTERBOX to hw_modes.h
For new side by side letterbox display mode
* Added VR_SIDEBYSIDELETTERBOX to hw_vrmodes.cpp
For Side By Side Letterbox display mode
This allows proper dimensions in the stock menus and should make menu layout for mods a lot easier because coordinates are more predictable than with the clean factors.
The feature is opt-in for custom content. As long as only stock elements are used, the menu will be able to switch between both on its own, but as soon as custom classes or custom elements are used, the virtual size must be declared explicitly, defaulting to clean scaling.
* Merged chat and scoreboard bindings into a "Multiplayer" submenu.
* Reordered items by importance. Chat at position #2 was nonsense.
* Moved weapon state actions from "Action" to "Weapon" menu, because the menu was already quite large and these are not standard actions.
Sensitivity scaling of both axes is now exposed as a raw factor to the user instead of obscuring it behind an unclear 'prescale' boolean.
This also consolidates the coordinate processing code to prevent such discrepancies as were present here from happening again.
Migration code for old config settings is present so that this change does not affect existing configurations.
The option effectively disables per frame mouse checks.
The motivation to add it was that many wireless mice 10-15 years ago had update rates of less than 35Hz, and on these it was necessary to sync mouse input with the playsim to properly interpolate between updates.
Today this is totally useless and even counterproductive because modern mice have significantly higher update rates, so this option no longer smoothes things but instead makes the mouse feel more choppy.
This simulates a feature found in Crispy Doom, which keeps the
weapon bobbing while firing. This leads to a "smoother" appearance
which may look a bit prettier to some people.
The default value of 0 preserves the old behavior.
