With new bundle adjustment based on Ceres we don't need
SSBA library anymore. This also means we don't need ldl
library and libmv is no longer depends on colamd as well.
Patch originally written by me, then finished by Sergey. Big
thanks to Sergey for troopering through and fixing the many issues
with my original (not compilable) patch.
The Ceres implementation uses 2 parameter blocks for each camera
(1 for rotation and 1 for translation), 1 parameter block for
common intrinsics (focal length etc) and 1 parameter block for
each track (e.g. bundle or 3D point).
We turn on some fancy optimizer options to get better performance,
in particular:
options.preconditioner_type = ceres::SCHUR_JACOBI;
options.linear_solver_type = ceres::ITERATIVE_SCHUR;
options.use_inner_iterations = true;
options.use_nonmonotonic_steps = true;
options.max_num_iterations = 100;
Special thanks to Sameer Agarwal of Ceres fame for splitting out
the SCHUR_JACOBI preconditioner so that it didn't depend on
CHOLMOD. Previously we could not use that preconditioner in
Blender because CHOLMOD is too large of a dependency for Blender.
BundleIntrinsicsLogMessage:
- Moved bunch of if(foo) LG << "bar" into this function, to make
EuclideanBundleCommonIntrinsics a little bit easier to follow.
EuclideanBundle:
- Fix RMSE logging.
While it's not a good idea to create convex hull shapes from objects
with no volume, this makes them behave a little nicer.
Fixes [#34410] Planes with Rigid Body always keep distance to colliding objects
- Fill in image dimension for camera intrinsics used for
solution refirement.
- Retrieve K3 from camera intrinsics after refining.
Shall be no functional changes, just makes things clear
and robust for further improvements.
structure instead of passing all the parameters to every function.
Makes it much easier to tweak distortion model.

- Moved keyframes and refirement flags into reconstruction options structure
- Moved distortion coefficients and other camera intrinsics into own structure
- Cleaned up reconstruction functions in libmv c-api

This is helpful because it brings CHOLMOB-free ITERATIVE_SCHUR and
SCHUR_JACOBI which is really nice for new upcoming bundle adjustment.
If also includes all the local fixes we made locally.
There're lots of other improvements/fixed which are not currently
would be so much visible in Blender, but which opens doors for some
great improvements in future.
This updates minilzo from version 2.03 to version 2.06 which
is like 3 years newer.
The main reason of this update is that older minilzo had some
strange valgrind warnings. Likely they're harmless, but it was
still annoying to troubleshot bakes with valgrind.
Was incorrectly testing for a vertex in a set with BLI_ghash_lookup
rather than BLI_ghash_haskey; the key in this case is always null so
the test failed.
This could leave the PBVH in an inconsistent state, since the
top-level map of BMesh vertices to PBVH nodes would indicate the
vertex was in a node, but that node wouldn't actually have any faces
using the vertex. That inconsistent state would eventually lead to a
crash in pbvh_bmesh_vert_remove().

Border select in UV Image window crashed, if used when Image Window shows a render.
Made operators for UV vertex manipulations having a more strict check for this mode.
(Similar to other UV tools there).
Notes:
* Everything is still a bit raw and sometimes hackish.
* Not every feature implemented yet.
* A bunch of cleanup is still needed.
* Doc needs to be updated too!
changing the screen resolution wasn't still allowed for larger virtual desktops.
added an exclusive option to ghost so the fullscreen window is ignored by the window manager and we get all events. (common practice for games on X11).
For the simulation to work properly the limited update the motion paths
calculation did wasn't enough so you got different results for for
motion paths than for the actual simulation.
Now do full frame update if rigid body sim is active.
TODO investigate if we can still limit this.
