//! The defines for different operating system are:
//! _IRR_WINDOWS_ for all irrlicht supported Windows versions
//! _IRR_WINDOWS_API_ for Windows or XBox
//! _IRR_LINUX_PLATFORM_ for Linux (it is defined here if no other os is defined)
//! _IRR_SOLARIS_PLATFORM_ for Solaris
//! _IRR_OSX_PLATFORM_ for Apple systems running OSX
//! _IRR_IOS_PLATFORM_ for Apple devices running iOS
//! _IRR_ANDROID_PLATFORM_ for devices running Android
//! _IRR_POSIX_API_ for Posix compatible systems
//! Note: PLATFORM defines the OS specific layer, API can group several platforms

//! DEVICE is the windowing system used, several PLATFORMs support more than one DEVICE
//! Irrlicht can be compiled with more than one device
//! _IRR_COMPILE_WITH_WINDOWS_DEVICE_ for Windows API based device
//! _IRR_COMPILE_WITH_OSX_DEVICE_ for Cocoa native windowing on OSX
//! _IRR_COMPILE_WITH_X11_DEVICE_ for Linux X11 based device
//! _IRR_COMPILE_WITH_SDL_DEVICE_ for platform independent SDL framework
//! _IRR_COMPILE_WITH_CONSOLE_DEVICE_ for no windowing system, used as a fallback
//! _IRR_COMPILE_WITH_FB_DEVICE_ for framebuffer systems

//! Passing defines to the compiler which have NO in front of the _IRR definename is an alternative
//! way which can be used to disable defines (instead of outcommenting them in this header).
//! So defines can be controlled from Makefiles or Projectfiles which allows building
//! different library versions without having to change the sources.
//! Example: NO_IRR_COMPILE_WITH_X11_ would disable X11
