Merging r38993 through r39028 from trunk into sox-2011-tomato

Fixed a small problem with the Fix Deforms op involving the case where a weight was zero.
Adjusted the distance limitations on the UI to be more reasonable.

Camera tracking integration
===========================

- Request from Sebastian/Francois: default lens
for clip set to 24.0
- Added some additional camera presets from Francois request.
Not sure all things from GENERIC section of that request
would be actually useful.

Probably the whole sensor size workflow would be changed...

Camera tracking integration
===========================

- Added function to calculate per-track average error.
Made this in libmv c-api, probably should be ported
to libmv pipeline.
- MovieTrackingTrack now holds average reprojection error
which is displayed in Active Track panel and information
text in clip editor (if displaying of names are enabled).
- Make "Clean Tracks" take average error on account.

Camera tracking integration
===========================

- Fixed bug with resetting marker's flag for non-transforming
tracks when canceling transformation.
- Fixed bug with keyframing non-selected tracks when initializing
tracking tools.
- Changed selection policy: now invisible parts of marker
can be selected.
- Added operator redo panel to Clip Editor.
- Set Scale operator now uses operator property for scale.
- Added operator "Clean Tracks" which currently checks if tracks
are tracked long enough and can select bad tracks, delete them
or delete tracking segments which are too short.

Clarifying tooltips on userpref keyframing options

These probably still need a good review (based on discussions I've had
with animators), but this should be a good stop-gap measure in the
mean time

Bassam Feature Request: "Auto Clamped" handles can now be set per
handle/key

This used to be a weird per-curve setting which would happen to get
applied/work correctly if handles were set to "auto", and was a source
of constant confusion for both old and new animators. The main effect
of this handle-type/option was really to just ensure that auto-handles
stayed horizontal, instead of tilting as the keys were moved.

This commit simply changes this from a per-curve to per
keyframe/handle setting.

Bugfix: Setting of new default settings for new Graph Editors was done
in wrong place, leading to loss of settings everytime the view changed
(i.e. after open/saving)

3D Audio GSoC:
Implementation of Julius O. Smith's resampling algorithm for high quality audio resampling.

The filter currently is a sinc filter with a 0.9 cutt-off and windowed by a kaiser window (beta = 10).
Also includes minor changes in the linear resampler.

fix for building with clang. makesrna wasnt linking with sqrt

Typo when reading line curving. The subversion is 1, so smaller than 1 should be converted

remove append to cursor code, wasnt used and made some naive assumptions about object locations.

UserPref/Node editor feature: Change the level of noodle curving.

Some people like curved lines, other hate them. This commit will let the user change the level of curving.

In UserPreferences=>Themes=>Node editor=>Noodle curving the level can be modified. Allowed range is 0-10 with the default on 5

The patch will default everything to the way blender works ATM.
File subversion has been increased otherwise older 258 files got straight lines.

The data is stored in the ThemeSpace.noodle_curving
the bezierdrawing is done in the drawnode. Also tested the Line cut tool

rst API doc fixes: literalincluding bge.texture and bge.constraints examples + bgl fixes

when appending with a NULL context dont print warnigns about scene not being set - was annoying for BGE LibLoad.

patch from jensverwiebe to disable ndof if header is not found.

3D Audio GSoC:
* versioning stuff for btheme->tv3d.speaker
* separating object.c speaker functions in own source file

Thanks Brecht for the suggestions.

Dynamic Paint:
* Smudge now works properly with substeps.
* Velocity brush speed clamping now works for all brush types.
* Small tweaking on velocity brush ui.

stricter guards for disabling NDOF code (will test in 3.. 2.. 1..)

fix [#28114] Render Crash

existing check for driver to use GIL was not thread safe and could cause, details in the report.

This bug was caused by a check to avoid hanging, a fix for [#27683] that worked in 2.4x because the UI didn't use python to draw while rendering.

Apply a different fix for [#27683], when calling an operator, call PyEval_SaveThread(), then PyEval_RestoreThread() so the GIL can be aquired by threads started by the operator - in this case bake starting a thread that evaluates drivers.
