* Fix for silly crash in point density UI, showed up in files with an existing empty texture.

Comments for text editor functions. More to come tomorrow.

Grease Pencil Bugfix

When converting to armature, don't flag the first bone of each stroke as connected.

patch [#17772] Fluid solver not built with OpenMP in Makefile build system

merge runk 16887:16950

Use xrange() rather than range() for loop iterations.

A fix for bug #8814:
http://projects.blender.org/tracker/?func=detail&atid=125&aid=8814&group_id=9

Smarter handling of faces that have a material index that points
to a null material.

* New point density update: Turbulence

This addition allows you to perturb the point density with noise, to give
the impression of more resolution. It's a quick way to add detail, without
having to use large, complex, and slower to render particle systems.

Rather than just overlaying noise, like you might do by adding a secondary
clouds texture, it uses noise to perturb the actual coordinate looked up
in the density evaluation. This gives a much better looking result, as it
actually alters the original density.

Comparison of the particle cloud render without, and with added turbulence
(the render with turbulence only renders slightly more slowly):

Using the same constant noise function/spatial coordinates will give a
static appearance. This is fine (and quicker) if the particles aren't
moving, but on animated particle systems, it looks bad, as if the
particles are moving through a static noise field. To overcome this, there
are additional options for particle systems, to influence the turbulence
with the particles' average velocity, or average angular velocity. This
information is only available for particle systems at the present.

Here you can see the (dramatic) difference between no turbulence, static
turbulence, and turbulence influenced by particle velocity:

one-liner fix for id property duplication bug

* dont change handle types when adjusting the radius or tilt of a curve handel.
* dont take the handles into account for the manipulator center when they are not drawn.

Bugfix:

Grease Pencil sketches in OGL-render should only show up if they were enabled for the original 3d-view.

fix for [#17560] Error in BPY_run_python_script
any path starting with a '.' on win32 would be replaced with C: (or the default root)
this was added rev 6568 so the file selector would replace "." with C:. should be moved to fileselector but for now compare with "." rather then checking the first char.

header_view3d.c - prop edit and render were aligning in curve edit mode.

fix for own bugs in curves.
- the number of segments was always 1 too many on cyclic curves.
- [#17739] - normals were not being calculated when rendering curves.

Replaced macro DL_SURFINDEX with a function. it that assumes variable names and could break from the loop that called it.

use uint8_t and uint32_t rather then Uint8 and Uint32, (mingw didnt know about Uint's)

whitespace commit

* use env.Clone() instead of deprecated env.Copy()

* merge main SConstruct and some of the utility scripts for our scons build from trunk.
Note: I'll be working on improving our scons build environment in this branch
Note2: I'll be upgrading our scripts to work fully with scons 1.0 (and possibly later)

=== SCons ===

* small doc update

== FFMPEG ==

Added optional OGG / theora / vorbis support.
(OGG-format encoding is currently disabled, since the bundled ffmpeg version
is broken here)

Fixed a bug with PTS-encoding, to make theora work.

You have to explicitly enable it and currently only scons is supported.

Otherwise: enjoy! :)

Python API
----------
Change documentation for Object.getSize(), Object.getEuler(), Object.getLocation() to clear up confusion about 'localspace' parameter.
