+Subject: Fix pixmap double-frees on error paths.
+
+If AddResource fails, it will automatically free the object that was
+passed to it by calling the appropriate deleteFunc; and of course
+FreeResource also calls the deleteFunc. In both cases it's wrong to call
+the destroy hook manually.

+Subject: Remove the SendEvent bit (0x80) before doing range checks on event type.
+
+Some extension libraries may set this bit before converting the event to
+wire protocol and as such range checking the event will cause an invalid
+BadValue error to result. As the documentation suggests the the bit
+should be "forced on", remove it before doing range checks and continue
+to force it on in the server.
