svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r19820:HEAD Notes: * Game and sequencer RNA, and sequencer header are now out of date a bit after changes in trunk. * I didn't know how to port these bugfixes, most likely they are not needed anymore. * Fix "duplicate strip" always increase the user count for ipo. * IPO pinning on sequencer strips was lost during Undo.
