===========================
Commiting camera tracking integration gsoc project into trunk.
This commit includes:
- Bundled version of libmv library (with some changes against official repo,
re-sync with libmv repo a bit later)
- New datatype ID called MovieClip which is optimized to work with movie
clips (both of movie files and image sequences) and doing camera/motion
tracking operations.
- New editor called Clip Editor which is currently used for motion/tracking
stuff only, but which can be easily extended to work with masks too.
This editor supports:
* Loading movie files/image sequences
* Build proxies with different size for loaded movie clip, also supports
building undistorted proxies to increase speed of playback in
undistorted mode.
* Manual lens distortion mode calibration using grid and grease pencil
* Supervised 2D tracking using two different algorithms KLT and SAD.
* Basic algorithm for feature detection
* Camera motion solving. scene orientation
- New constraints to "link" scene objects with solved motions from clip:
* Follow Track (make object follow 2D motion of track with given name
or parent object to reconstructed 3D position of track)
* Camera Solver to make camera moving in the same way as reconstructed camera
This commit NOT includes changes from tomato branch:
- New nodes (they'll be commited as separated patch)
- Automatic image offset guessing for image input node and image editor
(need to do more tests and gather more feedback)
- Code cleanup in libmv-capi. It's not so critical cleanup, just increasing
readability and understanadability of code. Better to make this chaneg when
Keir will finish his current patch.

Further development of small features would be done in trunk, bigger/experimental
features would first be implemented in tomato branch.
- remove unneeded type check from convert grease pencil operator.
- correct some error prints & use __func__.
- make copy_libblock take an ID* argument rather than void*.
this works by tagging functions, eg:
def my_func(scene):
pass
bpy.app.handlers.permanent_tag(my_func, True) # <-- important bit
bpy.app.handlers.frame_change_pre.append(my_func)
* Adds two new python handlers: scene_update_pre() and scene_update_post()
These run before and after Blender does a scene update on making modifications
to the scene.
* Datablocks now have an is_updated property. This will be set to true in the
above callbacks if the datablock was tagged to be updated. This works for the
most common datablocks used for rendering: object, material, world, lamsp,
texture, mesh, curve.
* Datablock collections also have an is_updated property. If this is set, it
means one datablock of this type was added, removed or modified. It's also
useful as a quick check to avoid looping over all datablocks.
* RenderEngine.view_update() can also check these properties, for interactive
viewport rendering.

* This adds a Rendered draw type in the 3D view, only available when
the render engine implements the view_draw callback.
* 3D view now stores a pointer to a RenderEngine.
* view_draw() callback will do OpenGL drawing instead of the viewport.
* view_update() callback is called after depsgraph updates.
- remove redundant casts
- replace strcmp's with "" to just check first char.
- added WM_event_print(), debug mode only to print events since the structs values are not that meaningful.
- added warnings if locale/font dirs cant be found.
Previous state:
Right now, there are "memories" of the "old" (less than a month!) translation way:
* A few remaining calls to BLF_gettext() (only UI_translate_do_iface and UI_translate_do_tooltip should be used).
* The _() macro still also calls BLF_gettext()!
New state:
Here are the changes made by the patch:
* Removing the no more needed _() macro.
* Removing most N_() and _() calls, only keeping the few needed ones (i.e. strings that are in no other way findable by xgettext and/or update_msg script).
* Defining in UI_interface.h IFACE_() and TIP_() macros (resp. for UI_translate_do_iface and UI_translate_do_tooltip).
* Replacing all calls to BLF_gettext by relevant IFACE_ or TIP_ one.
* Replacing all calls to UI_translate_do_iface by IFACE_.
* Replacing all calls to UI_translate_do_tooltip by TIP_.
All this somewhat clarifies and simplifies the code.
On the bf-translations scripts side, this only implies adding IFACE_ and TIP_ as detection markers for xgettext.
It also allows to reduce POTFILES.in quite notably (only 20 files remaining in it).
