> - Added compositor node "Movie Clip".

> camera uses non-default sensor size.
> - Track preview widget is now resizeable.
> - Marker position could now be adjusted from track preview widget.
> - Changed behavior of "Follow Track" constraint for tracks.  Now 
> tracking coordinates are mapped to plane which is parallel to camera 
> view plane.
> - Added option to show tracks names and their states (disabled, 
> keyframed, estimated, tracked).
> - Do not show bundles in 3d viewport if "Only Render" option is enabled.
> - Selected bundles are now highlighted with outline. It looks more 
> Blender-way of highlighting selected items.
> - Added option to show bundles names in 3D viewport.
> - Bundles now could be selected from 3D viewport.
> - Tweaked "Snap Cursor To Selection" operator: If selected object is 
> camera and there's bundles visible in viewport, snapping would use 
> midpoint of selected bundles.
> - Option to lock tracks. Locked tracks can't be be moved, scaled, 
> re-tracked and so.
> - Added setting for shape of bundle. Default is sphere.
> - Test feature: configurable marker colors in Clip Editor. Use 
> presets, so plenty of different color could be defined and easily re-used.
> - Added option to show distortion grid. It's most probably temporary 
> solution until [auto]calibration tools aren't merged. This grid 
> defines straight lines on the image.
> - Movie Clip display aspect ratio is now available on Display panel.
> - Refactor of context structure used for 2D tracking:
>   * Tracker object is now per-track. This allows to use different 
> pyramid levels for different tracks and now search area resizing 
> shouldn't make tracking less accurate.
>   * This is also be used for new optimized libmv API.
>   * This allowed to use OpenMP to track different markers in separated 
> threads. This allowed to reach quite cool speedup for multi-core CPU.
> - Added modifier key for marker transformation: if alt is pressed down 
> -- pattern/search will be moving relative to marker center.
> - Changed behavior of mouse sliding:
>   * To change marker position markers should be slided by it's center.
>   * Left-top corners now used to offset pattern/search relative to 
> marker center.
>   * Hide mouse cursor during sliding.
> - Operator "Join Selected Tracks". This operator joins all selected 
> tracks to active track. Hotkey is Ctrl-J.
> - Operator "Select Grouped". Now it's easy to select all 
> locked/keyframes/etc markers. Hotkey is Shit-G.
> - Operator to jump to beginning/end of active path. Hotkeys are 
> Shift+Ctrl+Arrow Left/Right.
> - Operator to copy color from active track to all tracks.
>> 2) what you will do next week
> - Continue proxies integration. haven't got enough time this week.
> - Make markers "animatable" (in terms of changing size when tracking. 
> discusses in libmv-devel)
> - Integrate markers with dopesheet and fcurve editors. Have several 
> requests here.
> - libmv team is heavily working on api now. I hope new optimized 
> tracking would be allowed.
> - As i understand new features like marker rotation would be needed.
> - Most probably additional work on changing current things to match 
> artists workflow would be needed.
>> 3) any problems that will require extra attention and the impact on your proposed schedule
> There were no new problems this week.
