This operator (Ctrl-F) allows you to flip the lattice coordinates without
inverting the normals of meshes deformed by the lattice (or the lattice's
deformation space for that matter). Unlike the traditional mirror tool, this
tool is aware of the fact that the vertex order for lattice control points
matters, and that simply mirroring the coordinates will only cause the lattice
to have an inverted deform along a particular axis (i.e. it will be scaling by a
negative scaling factor along that axis).
The problems (as I discovered the other day) with having such an inverted
deformation space are that:
- the normals of meshes/objects inside that will be incorrect/flipped (and will
disappear in GLSL shading mode for instance)
- transforming objects deformed by the lattices will become really tricky and
counter-intuitive (e.g. rotate in opposite direction by asymmetric amounts to
get desired result)
- it is not always immediately obvious that problems have occurred
Specific use cases this operator is meant to solve:
1) You've created a lattice-based deformer for one cartoonish eye. Now you want
to make the second eye, but want to save some time crafting that basic shape
again but mirrored.
2) You've got an even more finely crafted setup for stretchy-rigs, and now need
to apply it to other parts of the rig.
Notes:
* I've implemented a separate operator for this vs extending/patching mirror
transform tool as it's easier to implement this way, but also because there are
still some cases where the old mirroring seems valid (i.e. you explicitly want
these sort of distortion effects).
* Currently this doesn't take selections into account, as it doesn't seem useful
to do so.

Usage: In weight paint mode, select the mesh to have its weights culled. Click on "Limit Weights" button. A sub-panel will appear "Limit Number of Vertex Weights" with a slider field "Limit" which you can set to the appropriate level. The default level is 4, and it gets executed upon pressing "Limit Weights" so you will need to do an "undo" if your max bone limit is above 4. The checkbox "All Deform Weights" will consider all vertex weights, not just bone deform weights.
Added a convenience operator to the Follow Path constraint which adds a F-Curve
for the path (or the operator's "fixed position" value if no path is assigned),
with options for setting the start frame and length of motion. This makes it
easier for common users to just set up a quick follow-path animation where the
camera (e.g. flying around a set over certain number of frames).
A key advantage of this is that it takes care of the underlying math required
for setting up the generator curve accordingly (I've got some plans for making
this a bit friendlier to use later). Now, animating the paths is a one-click
operation, with the start and length properties able to be controlled using the
operator properties.
* Get rid of ED_object_add_generic_invoke() and all invoke callbacks using it, it was doing nothing exec() callbacks would not do. In fact, its only action (setting part of common add ops properties, like loc, layers, etc.) was needed too by direct exec call, so it was done twice in case of using invoke()!
* Replace custom invoke code for metaballs by WM_menu_invoke helper (as already used by lamps).
* Add a new OBJECT_OT_empty_add op, to allow direct addition of empties of a given drawtype.
* And some general code cleanup (like trailing spaces, empty lines, ...).
Did quite a bunch of tests/verifications, but obviously could not tackle all possible scenarios... Anyway, if any, bugs should arize quite quickly (but I don’t expect any! :p ).
* The operator creates bones for each input edge (does not subdivide
them like the skin operator does), adds a fake root bone for skin
roots with multiple children.
* The operator adds vertex weight groups to the original mesh.
* Make copy_object_transform() public, used to match the armature
object to the mesh object.

vertex_group_transfer_weight_exec() governs all.
Functions renamed/added with _transfer_weight_
as opposed to _copy_by_
This is to reflect changes in parameters and usage as the internal code will change.
* Added proper "update" operators in place of the abuse of the calculate
operators, so now the display ranges won't get overwritten everytime (with the
default values) you go to update the paths.
* Display range settings in properties editor now actually work. Before, the "In
Range" mode only displayed the entire paths.
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/
- removed some unused functions.
- renamed vars to make more sense paint_vertex.c 'flags' --> 'lock_flags'
- some odd modifications were made in unrealted, commented code, copy these back from trunk.
- rename vertex_group_fix 'cp' property to 'accuracy'
- make style more consistant with trunk.
- remove 'Radish' comments.
