|
|
*
|
|
* 6 6/03/99 6:37p Dave
|
|
* More TNT fun. Made perspective bitmaps more flexible.
|

*
|
|

|
|
* 114 5/16/98 2:20p John
|
|
* Changed the os_suspend and resume to use a critical section to prevent
|
|
* threads from executing rather than just suspending the thread. Had to
|
|
* make sure gr_close was called before os_close.
|
|
*
|
|
* 113 5/15/98 4:49p John
|
|
*
|
|
* 112 5/15/98 3:36p John

|
* Revamped the whole window position/mouse code for the graphics windows.
|
|
*
|
|
* 110 5/04/98 11:08p Hoffoss
|
|
* Expanded on Force Feedback code, and moved it all into Joy_ff.cpp.
|
|
* Updated references everywhere to it.
