Action Editor Bugs/Regressions:

* Insert Key and Column Select should be working again
* Last channel in group's keyframes now appear in summary too

Fix for indirectly linked libraries.

When a.blend -> //../c.blend -> //d.blend
Blender would see d.blend as //d.blend which is wrong since that is relative to c.blend
This works, except when you make an indirectly linked group into a directly linked group. and then the incorrect path was saved into the blend file and the data not load up again (without copying it there or hex editing the path)

This loop makes all lib files relative to the blend you have open.

== Sculpt ==

Switched point projection used in brush texturing to floating point rather than integer; fixes some ugly artifacts in texture application.

More logging prints while preparing scenes in background render.
Uses a timer, so nothing gets printed more than once a second.

- Bugfix in non-osa pass adding, for example AO got too high values.
Now made it work more like the osa case, easier to verify it works
correct then.

Fix: render could crash when you enable 'do composite' without having
nodes in scene.

Feature: SHIFT+R in compositor reloads all full sample buffers, composites
and merges with filter. (ALso in Node menu).

== Sequencer ==

Updated image preview a lot:
* Added a histogram-scope
* Added optional title-safe margins
* Re-arranged header, so that only usefull buttons are shown in image
preview mode
* Added zebra-mode for visual feedback of over-exposure regions
(helps in before and especially after color correction :)
* Added color-seperation-mode for waveform-display
* Show 10%, 70% and 90% hints in waveform-display

Added missing header for offsetof function.

Stupid error in commit of last weekend for zmasking:
You could not mask out anymore using the 'ctrl-click layer' without
having zmask on.

Replaced all *f geometric functions like sinf etc. with sin etc. (were used in 2 functions from the gnu scientific library)

Fix: Compiling should work on SOLARIS again.

Bugfix for Join Armatures:

When Join Armatures was called from the menu (Object -> Join Objects) problems were being cause by the use of BASEACT, causing some armatures to disappear and not be joined.

== Bone Groups - Outliner Support ==

Bone groups are now drawn in the Outliner. The active group can be set from there, and groups can be renamed.

(Hah... that was easy)

Forgot to commit changes in header for previous Action Editor commit

Action Editor Bugfix:

Constraint Channels now have editable keyframes again. In the process, I've tweaked the Action Editor filtering logic a bit, so some regressions with other tools may have been caused.

Bugfix #8070: blender crash when assigning driver to bone constraint

When there were no keyframes for a constraint on a bone, trying to add a driver to the influence curve would fail, as a new curve would be added the some mysterious place. The cause was a missing case, as the code assumed that no user would try to add from IPO-Editor in such a way.

Cloth bugfix: enable stiffness scaling again even if cloth is not pinned

Fixes in reading back rendered temp files ("Save buffers" and "FSA" options).

Press Rkey in compositor for reading back render results and invoke a compo.
This now correctly reads AO (skipped it sometimes) and it makes a correct
composite.

FSA todo:
- hotkey + button for reading all samples back + composite
- solve black border around image

== MSVC 7.1 projectfiles ==
- added missing files from cloth sim

Speedup of filereading: when using large libraries (referenced data from
other blend files) lookups of data slowed down tremendously.
Added another bsearch for speedup. Makes a difference here (200+ MB files)!
