//
// Version History:
//
// TenebraeQuake:
// v1.0.0: Initial release.
//
// Standard Quake branch [pre-TenebraeQuake]:
// v1.0.8: Fixed an issue with the console aspect, if apspect ratio was not 4:3.
// Added support for gl_arb_multisample.
// v1.0.7: Brings back the video options menu.
// "vid_wait" now availavle via video options.
// ATI Radeon only:
// Added support for FSAA, via variable "gl_fsaa" or video options.
// Added support for Truform, via variable "gl_truform" or video options.
// Added support for anisotropic texture filtering, via variable "gl_anisotropic" or options.
// v1.0.5: Added "minimized in Dock" mode.
// Displays are now catured manually due to a bug with CGReleaseAllDisplays().
// Reduced the fade duration to 1.0s.
// v1.0.4: Fixed continuous console output, if gamma setting fails.
// Fixed a multi-monitor issue.
// v1.0.3: Enables setting the gamma via the brightness slider at the options dialog.
// Enable/Disable VBL syncing via "vid_wait".
// v1.0.2: GLQuake/GLQuakeWorld:
// Fixed a performance issue [see "gl_rsurf.c"].
// Default value of "gl_keeptjunctions" is now "1" [see "gl_rmain.c"].
// Added "DrawSprocket" style gamma fading at game start/end.
// Some internal changes.
// GLQuakeWorld:
// Fixed console width/height bug with resolutions other than 640x480 [was always 640x480].
// v1.0.1: Initial release.
