Fullscreen window was incorrectly placed on the main screen instead of the current one
Honestly I have no idea what was the reason behind that [NSWindow setFrameOrigin:] call
Apparently it's redundant and moreover it's incorrect for multi-monitor configuration
Independently from OS version the game will enter fullscreen mode when zoom button is clicked
Window zooming behavior introduced in Yosemite is available on all supported versions of OS X
Native OS X backed didn't center mouse cursor in fullscreen mode with Retina/HiDPI support enabled
Incorrect size of content view led to placement of cursor in upper right corner of the screen upon releasing of mouse capture
When some action is assigned to this corner using system Hot Corners feature, the given action was triggered on acquiring mouse capture
There are a few quite specific steps to reproduce this issue:
* 640x480 video resolution
* -iwad ... -warp ... command line parameters
* OS X 10.4 or 10.5 PowerPC, maybe performance related
When all these requirements are met, content view doesn't show up sometimes
The simplest solution for this issue is to set initial window size to non-existent video resolution
