Blender Git Loki

merging game_engine branch changes into trunk, 2d-filters and opengl speedup

Bugfix:

AfterTrans Delete Duplicates feature for Action Editor now doesn't remove duplicates if you cancelled the transform.

Python API
----------
Correct sound into font in documentation to api2_2x/doc/Font.py.

* Change to the 'active line' drawing in colourbands. The wide strip was always ugly, inaccurate and jumped around. Now it uses a finely dashed line.

* Let HDRs get previewed by the image browser too

Cloth: Fixed: [#8210] (includes bad spring calculation), only mesh can get cloth assigned, New: initial try of Bridson/Fedkiw friction formula implementation, better GUI feedback when e.g. cache is protected and settings too

Added single user ipos option - useful when you make linked duplicates with many objects and want them a unique ipo.

fix for bug [#8065] Crash when baking.
http://projects.blender.org/tracker/index.php?func=detail&aid=8065&group_id=9&atid=125

Lamp ray_samp_method could be an invalid value while rendering because a check was only done in the user interface.

== Sequencer ==

Fix for the fix.

== Sequencer ==

Silenced compiler warnings and possibly fixed crash on broken
blend files.

== Sequencer ==

Silently destroyed a null check in free_sequence in last commit,
getting old... :)

feature request from peach, remove selected objects from 1 group.
Also made rem_from_group return if it removed the object which save some looping.

Added a node in the blender help message that background mode dosnt load the .B.blend file as a bug was reported recently because of this.

== Sequencer ==

This adds low resolution proxy support to the blender sequencer, so
that even HD editing should be possible on slower machines.

The proxies are stored as directories of JPEG-files and are only
activated, if you use preview-resolution rendering.

For your final render, just switch back to full resolution and
the original files are used again.

It enables even proxying of whole effect pipelines and scene-strips
(but you have to your own custom directory for file storage then,
since blender has no filename, which could be taken as a sensible
default directory reference)

More fixes for gcc warnings.

=== Custom Transform Orientation ===

Switch away from using selected list in editmesh, since it isn't always up to date.

This fixes the bug where CTO where not created correctly with box/lasso selecting elements and many others.

Use proper projection for contrained scale snapping.

2 Tweaks:
* Action Editor now doesn't draw channels which are out of view at all, which should help to provide (some minimal) improvements in some situations
* Typo in comment in constraints code

Missed reverting one extra assignment.

Clean-up for various gcc warnings under linux.

Python API
----------
renderData.removeRenderLayer() was not returning a Python object; make it
return None;
