(in-package goal)

#|

  This file contains new code that we need for the PC port of the game specifically.
  It should be included as part of the game engine package (engine.cgo).

  This file contains various types and functions to store PC-specific information
  and also to communicate between the game (GOAL) and the operating system.
  This way we can poll, change and display information about the system the game
  is running on, such as:
  - display devices and their settings, such as fullscreen, DPI, refresh rate, etc.
  - audio devices and their settings, such as audio latency, channel number, etc.
  - graphics devices and their settings, such as resolution, FPS, anisotropy, shaders, etc.
  - input devices and their settings, such as controllers, keyboards, mice, etc.
  - information about the game window (position, size)
  - PC-specific goodies, enhancements, fixes and settings.
  - whatever else.

  If you do not want to include these PC things, you should exclude it from the build system.
