properties values from previous operator run instead of using values
from tool settings.

No-proxied frames using for 2D tracking used to be putting to cache which lead
to extra memory usage which shouldn't happen.
|

- Fixed tooltip displaying for track sequence forwards in clip editor
- Corrected detection of 8 tracks so it wouldn't count tracks disabled
on keyframes.
- Scale track preview to actual track widget size instead of scaling the
whole preview image with given zoom ratio, so no extra memory needed to
store zoomed margin would be used.
- Track's statistics text will fit pattern position instead of search if
marker is disabled on current frame.
- Fixed toggle selection operator if selected track is hidden due to
"Hide Disabled" policy.

Issue was caused by recently added operator presets stuff.

This commit implements basic clipboard support for movie tracking data
int clip editor. Used own implementation of clipboard like it's done
for sequencer.
Ideally it needed to be switched to more general clipboard system, but
currently this system is designed for text data only and it need to
be re-designed itself. But this feature is quite useful since object
tracking is implemented, so it should be OK to live with such own
implementation for a while.

This commits merges object tracking implementation from tomato branch.
Summarized changes from branch:
- Added list of objects to be tracked. Default there's only one object called
"Camera" which is used for solving camera motion. Other objects can be added
and each of them will have it;s own list of tracks. Only one object can be used
for camera solving at this moment.
- Added new constraint called "Object Tracking" which makes oriented object be
moving in the save way as solved object motion.
- Scene orientation tools can be used for orienting object to bundles.
- Object has got scale to define "depth" in camera space.
- All tools which works with list of tracks or reconstruction data now
gets that lists from active editing object.
- All objects and their tracking data are available via python api.
- Improvements in witness cameras workflow,

Added slider to define scale of object solution which is used to define
"depth" of object relative to camera position. This slider effects on all
"users" of object solution such as bundles display, constrained objects and so.
Added new operator called "Set Solution Scale" to set real scale for object
solution based on real distance between two bundles reconstructed for this object.
New slider and operator can be found on "Object" panel in toolbox when in
reconstruction mode and active tracking object isn't a camera.

Also fixed incorrect poll functions which didn't check active object when orienting object.

inconsistent with similar functions & math notation:
mul_m4_m4m4(R, B, A) => mult_m4_m4m4(R, A, B)
mul_m3_m3m4(R, B, A) => mult_m3_m3m4(R, A, B)
For branch maintainers, it should be relatively simple to fix things manually,
it's also possible run this script after merging to do automatic replacement:

scene's camera
Made Object Solver operator parent object to scene's camera. Behavior is pretty much
familiar to Child Of constraint -- it stores inverted transformation matrix which gives
constant offset in parent's space.
Current files would open incorrect, to make object aligned well again, just press
"Set Inverse" button in Object Solver constraint.
Fixed orientation operators so now they should work in all cases.
Also changed behavior of Set Origin operator which now sets origin to the median
point of all selected tracks/

Malloc is getting to be safe on sequence tracking by the jobs system,
so no additional set up are necessary.
This hopefully fixes crash on OSX with OpenMP enabled when compiling by older gcc

This commit implements basis stuff needed for object tracking,
use case isn't perfect now, interface also should be cleaned a bit.
- Added list of objects to be tracked. Default there's only one object called
"Camera" which is used for solving camera motion. Other objects can be added
and each of them will have it;s own list of tracks. Only one object can be used
for camera solving at this moment.
- Added new constraint called "Object Tracking" which makes oriented object be
moving in the save way as solved object motion.
- Scene orientation tools can be used for orienting object to bundles.
- All tools which works with list of tracks or reconstruction data now
gets that lists from active editing object.
- All objects and their tracking data are available via python api.

This is possible fixes #29498: Seg fault on trying to track byond clip length

In some cases solving can take a while (especially when refining is used)
and keeping interface locked is a bit annoying. Now camera solver is moved
to job system and interface isn't locking.
Reporting progress isn't really accurate, but trying to make it more linear
can lead to spending more effort on it than having benefit. Also, changing
status in the information line helps to understand that blender isn't hang
up and solving is till working nicely.
Main changes in code:
- libmv_solveReconstruction now accepts additional parameters:
* progress_update_callback - a function which is getting called
from solver algorithm to report progress back to Blender.
* callback_customdata - a user-defined context which is passing
to progress_update_callback so progress can be updated in needed
blender-side data structures.
This parameters are optional.
- Added structure MovieTrackingStats which is placed in MovieTracking
structure. It's supposed to be used for displaying information about
different operations (currently it's only camera solver, but can be
easily used for something else in the future) in clip editor.
This statistics structure is getting allocated for time operator is
working and not saving into .blend file.
- Clip Editor now displays statistics stored in MovieTrackingStats structure
like it's done for rendering.

This commit implements:
- Configurable settings for newly creating tracks
Now it's possible to set tracking algorithm and it's settings for
all newly creating tracks including manual tracks creation and
tracks creation by "Detect Features" operator.
- Moves margin, frames limit and adjust frame inside per-track
settings.
Was request from Francois for this.
- Adjust Frames replaced with menu called Pattern Match where it's
possible to choose between matching pattern from keyframe frame
or from previously tracked frame.
Didn't see somebody used adjust frames values differ from 0 and 1,
and this menu should make things more clear here/

Added "Extend" flag to border select operators for editors:
- UV Editor
- Sequencer
- NLA
- Info Space
- Graph Editor
- File Browser
- Clip Editor
- Action Editor
- Channels and markers regions
Can be used for custom keymaps.

- Changed some names so now people who aren't really familiar with
motion tracking can understand what they exactly means
- Also cleaned up and rephraded some descriptions
- Changed behavior of operator which creates empty for 2d tracks:
now it operates on all selected tracks rather than active track only
- Added checkbox to enable/disable rotation stabilization

- Add support for refining the camera's intrinsic parameters
during a solve. Currently, refining supports only the following
combinations of intrinsic parameters:
f
f, cx, cy
f, cx, cy, k1, k2
f, k1
f, k1, k2
This is not the same as autocalibration, since the user must
still make a reasonable initial guess about the focal length and
other parameters, whereas true autocalibration would eliminate
the need for the user specify intrinsic parameters at all.
However, the solver works well with only rough guesses for the
focal length, so perhaps full autocalibation is not that
important.
Adding support for the last two combinations, (f, k1) and (f,
k1, k2) required changes to the library libmv depends on for
bundle adjustment, SSBA. These changes should get ported
upstream not just to libmv but to SSBA as well.
- Improved the region of convergence for bundle adjustment by
increasing the number of Levenberg-Marquardt iterations from 50
to 500. This way, the solver is able to crawl out of the bad
local minima it gets stuck in when changing from, for example,
bundling k1 and k2 to just k1 and resetting k2 to 0.
- Add several new region tracker implementations. A region tracker
is a libmv concept, which refers to tracking a template image
pattern through frames. The impact to end users is that tracking
should "just work better". I am reserving a more detailed
writeup, and maybe a paper, for later.
- Other libmv tweaks, such as detecting that a tracker is headed
outside of the image bounds.
This includes several changes made directly to the libmv extern
code rather expecting to get those changes through normal libmv
channels, because I, the libmv BDFL, decided it was faster to work
on libmv directly in Blender, then later reverse-port the libmv
changes from Blender back into libmv trunk. The interesting part
is that I added a full Levenberg-Marquardt loop to the region
tracking code, which should lead to a more stable solutions. I
also added a hacky implementation of "Efficient Second-Order
Minimization" for tracking, which works nicely. A more detailed
quantitative evaluation will follow.
Original patch by Keir, cleaned a bit by myself.

- Assume all areas are using valid MovieClipUser when using functions from movieclip.c
- Set active scene clip to movie-related nodes in compositor rather than checking
if there's only one clip in datablocks
- Fixed users count issue when solving camera motion

===========================
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.
More details about this project can be found on this page:
http://wiki.blender.org/index.php/User:Nazg-gul/GSoC-2011
Further development of small features would be done in trunk, bigger/experimental
features would first be implemented in tomato branch.
