nx-X11/programs/Xserver/hw/nxagent/CHANGELOG

 ChangeLog:
 
+nxagent-3.3.0-18
+
+- The area to restore from the backing store is limited by the screen
+  size instead of the visible screen.
+
+nxagent-3.3.0-17
+
+- Fixed TR12F02150. The agent could crash when copying text from VNC
+  viewer. Fixed by aborting the procedure in case the retrieved pro-
+  perty has not a valid format.
+
+nxagent-3.3.0-16
+
+- Fixed TR07G02247. Don't try to call XSetWindowColormap() if the
+  window has no colormap, e.g. if its class is InputOnly.
+
+nxagent-3.3.0-15
+
+- Fixed TR04G02210. Region is cut to the visible screen before re-
+  storing areas from the backing store.
+
+- Fixed TR07G02246. Box is shrinked if bounds can't stay in a short
+  signed integer.
+
+nxagent-3.3.0-14
+
+- Fixed TR03G02206. waitpid() call was missing for the "Fonts replace-
+  ment" dialog type.
+
+- Fixed TR03G02195. Added a properties structure compatible with 32
+  and 64 bit platform types.
+
 nxagent-3.3.0-13
 
 - Handle the window unmap immediately. Don't add it to the configure
