There is no good solution here, since RNA props can only have one type/unit.
Tried to find the less worse one - have different RNA props for same DNA value
(a bit like the angle/length for camera lens).
Also fixed two other issues with Transform conctraint:
* Angle were still in degrees (yes, another backward-compatibility breacking).
* Scale was absolute, unlike loc/rot.
Also cleaned up a bit the code, replaced some magic numbers by proper enums, ...
- ability to change the space the axis is projected in (so you can choose worldspace or -space, was always local-space before).
- support projecting on a negative axis, without this some very simple clamping is not possible if the direction happened not to be positive.
- add distance limit (same as modifier), without this single meshes surrounding an object would make the constraint impossible to use in some cases (it would snap to the wrong side).
note: this removes the ability to project on multiple axes at once but this option only added up directions and didnt project on multiple axes as you might expect.
purpose of some of these features
* ClampTo Constraint, Target Object field: now mentions that it is for curve
objects only
* Dopesheet Editor Modes: now describe what data is editable in each mode. The
wording may be a bit clumsy here, but (apart from Mask Editor one, which I'm not
entirely sure about) should at least be technically correct
* Rename Legacy to Standard, it's not being deprecated as far as I know.
* Make option to toggle off Location solving work with Standard.
* Make it converge a bit better in some cases by enforcing a minimum number of
iterations before giving up.
* Move IK solver choice out of bone panel, it's an armature level setting and
should be set there.
* Radiant -> Radians
* Noted down revision number for when Jahka removed the old constraint blending
logic. I spent some time hunting this down while trying to check if it might've
caused any obvious changes leading to one of the (now closed) bugreports. Better
to note this in the code then.
This is needed in cases when using blender camera with different
resolution than original footage. Behaves in the same way as
background picture framing.
* ID-blocks referenced by Constraints but not being used as the target objects
(such as Actions in the Action Constraint, or Text Blocks in PyConstraints) now
get usercounts for being referenced in this way. This should fix ancient bugs
such as [#19205] and [#8593]. More tests still needed to verify that this
does now play nicely with proxies.
* Changing actions used by NLA strips should now update the usercounts
accordingly
can type in any value, and only when sliding the number value there is a limit.
It was already possible to assign any value to a socket with node linking, so
this shouldn't cause any new issues.
Also raised the limits on the math nodes, with a patch by Agustin Benavidez.
This fix adds a "ref_id" ID pointer to BKE_all_animdata_fix_paths_rename() & co, which is the ID against which prefix+oldName/NewName is "applied", currently only used for drivers' bones targets. Just pass NULL to get same behavior as previously. A bit annoying to make such a change for such a specific case, but there seems to be no other way to go... :/
Note about long lines: I did not touch to two pieces of code (because I don’t see any way to keep a nicely formated, compact code, with shorter lines):
* The node types definitions into rna_nodetree_types.h
* The vgroup name functions into rna_particle.c
While looking at a bug report, I found that the current GUI for the Action
Constraint actually didn't make sense, mixing up settings so that it wasn't
clear which settings corresponded to which others. This commit cleans up the
layout into a clearer two-column design to have a "from" -> "to" layout, making
all the
relationships between things clear.

If this object is defined, object with Follow Track constraint would be
projected into surface of this depth object.
If object is not set or there's no projection onto it, projection plane
calculated based on original object position would be used.
This allows to make cheap facial mocap.
Object used to be parented to active camera which isn't very convenient when
working with witness cameras.
Now parent camera can be specified in constraint (if it's not specified, active camera is used)
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.
- Move tracking-related constraints to own section in list
Currently there are only two constraints, so can look a bit odd,
but it'll be other constraints like "Object Solver" and so.
- Move motion-tracking parameters from 3D viewport Display panel
to it's own panel.
- Get rid of "Bundle" in 3d viewport. It's quite obvious that it's
a 3D representation of tracks is used in 3D viewport and it shouldn't
be so confusing for artists now.
- Also get rid of "Bundle" in Follow Track constraint.
Old files can change a bit because of changes in DNA.
- Also get rid of "Bundles" in operator which creates vertices cloud
from 3D position of tracks.
- Rename "Principal Point" to "Optical Center" in the interface.
===========================
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:

Further development of small features would be done in trunk, bigger/experimental
features would first be implemented in tomato branch.
