- Fixing framerate on caps renegotiation. We memorize it on sinkconnect to set fixed caps on renego.

Original commit message from CVS:
- Fixing framerate on caps renegotiation. We memorize it on sinkconnect to set fixed caps on renego.
- Homogenized indentation.
- Removed some comments.
- Fixed the caps renegotiation new ximage creation (it was creating a new ximage on every configure event even if window's size has not changed)
- Removed pointer coordinates translation in navigation_send_event as we are not doing scaling. videoscale should convert those events is scaling there is.
