Revision:	1.19
Committed:	2003-12-31T18:16:55Z (20 years, 9 months ago) by gbeauche
Content type:	text/plain
Branch:	MAIN
Changes since 1.18:	+19 -0 lines
Log Message:	Add fast X11 display locking routines based on spinlocks, or on pthreads in the worst case. Optimize out GetScrap() case when we already own the selection. i.e. make it smoother. Use our own XDisplay{Un,}Lock() routines.
