Blender Git Loki

Lots of stupid warning fixes:
Added newlines at end of a bunch of files that didn't have them.
removed a couple of unused variables and an extra ';'
(Also removed config.h crap from these files)

I added {}'s around an if block of code to prevent gcc from saying
this else is ambiguous...
code was
if (blah) if (blah2) stuff; else stuff2;
its now
if (blah) { if (blah2) stuff; else stuff2; }

Bugfix for Toni: Ipo_addCurve() needed to call set_icu_vars() in order to
properly initialize data for new Ipo curves.

Orange bugfix; duplicating object with group didn't increase group user
counter... tsk tsk tsk!

orange bugfix: "Make local Action" did not set the Ipos in channels to
local (or make copy if used by other actions), causing in loss of ipo's.

Changed so all errors raise an excepton. - As per Toni's suggestions.
TypeError for pythonCoder error.
RuntimeError for blender not being able to be joined. (Sorry stivs, no BadJuJu yet)

Documented this in the epydocs also.

Three minor fixes:
- removed debugging output from fluidsim export
- directores with "+" are now valid for fluidsim data
- simulation now always uses frame 1 to endframe, so changing start frame settings should work again

Orange bugfix: regular materials did not show textures...

Orange: Ack! Yesterday's commit to cleanup relative paths forgot to
change the undo code as well... so on any Undo/redo all the libraries got
lost!

Orange; maintenance commit!

- Moved all 'render pipeline control' options out of the Material panels
into the (now renamed) "Links and Pipeline" Panel. These are the options
that are not per material-node, but global for the entire Material tree.
It includes ZTransp, Zinvert, Strands, Halo, Wire, etc.

- To further make Node editing clear, when you enable Nodes for the first
time, the link button to the first Material node is drawn red, to note
that here needs something linked or added.

- Protected Node editing for Library data

- Fixed header buttons to work OK for Node Window

* Fix to update timeline after transform in action window

Orange; last commit didnt draw passepartout correctly. Also added a limit,
so you cannot screw up the entire view :)

Orange: Hold SHIFT+MMB in camera view shifts the viewports around.

Orange; moved version patch for bone layers to 2.40, so orange branch can
read 2.40 files!

Orange; relative path fix for libraries.

- On linking stuff from libraries, each relative path now is relative with
respect to the file that uses the library.

This way you can make libraries that use other libraries, and link them
in your project with an entire different relative path.

The commit also fixes issues when mixing up relative or non-relative paths.

Now after this I need to commit something cool, so the orangers will update
and check! :)

[ #3661 ] resize4x4 in Matrix class doesn't set ones on the diagonal

* resizing a matrix now puts 1's back on the diagonals.

Wednesday sync orange with bf-blender

Note: has the crazyspace fix!

Fix for CrazySpace correction. (Special request of our Argentinan bird
movie friends :)

There were two issues with it, which both have been tackled as follows:

- the correction transformations (quaternions) were calculated per face,
and then averaged over the vertices. This gave annoying inaccuracies,
especially when the geometry is irregular.
The new code first calculates two tangent vectors in a vertex, based on
the associated edges it has in a face. These tangents then are used to
define the transform. Tangents are 20% of the length of an edge now.

- When a SubSurf modifier was in the chain, the deformation caused by the
subsurf was also included in CrazySpace correction, giving even larger
errors.
New code temporally disables Subsurf, recalculates vertices, and then
does the crazy tricks. :)

All in all, quite well working!

Added some notes regarding Object.GetSelected() - it uses the last localview.

[ #3712 ] Calling makeEditable() and update() on an armature twice duplicates bones

* fixes bug where editbones are not freed on calling update()
