Revision:	1.10
Committed:	2001-07-03T15:59:45Z (23 years, 4 months ago) by cebix
Branch:	MAIN
Changes since 1.9:	+7 -0 lines
Log Message:	- added support for platform-independant mutexes, currently only properly implemented under Unix - adb.cpp uses mutexes for thread-safe mouse handling - video_x.cpp: pressing Ctrl-F5 in windowed mode switches to a "grabbed" relative mouse mode, useful for some games - video_x.cpp: fixed some bugs relating to the hotkeys (key releases are no longer treated as hotkeys)
