The daily node commit: brought back panning background image.
For now it is on ALT+MiddleMouse. The view2d code eats the shift+mmb,
which is not necessary, but will have to ask Joshua to be sure.

Probably tomorrow it's shift+mmb as for 2.49.

Added tongue and neck rigs. The neck rig is quite solid, I think, and is working well in production on Durian. The tongue rig is a bit hacky, but I'm adding it for now since we're using it in Durian.
Also added pupil dilation to the eye rig type, and made the finger rig type work with two-digit fingers.

Auto Keyframing:

Made 'PoseLib', 'Pose Paste', and 'Transforms' use the active KeyingSet instead of a hardcoded one if there is an active KeyingSet and the 'Only Insert for Keying Set' option is enabled in the User Prefs.

Also, made sure that for transforms, the active KeyingSet is provided with the data being modified instead of having them retrieve this from the context (which may miss a few items).

---

While making the changes for pose paste, made pasting poses not destroy the existing properties on the bones if the buffer bones didn't have any properties to replace the old ones with. IMO, this seems a bit too destructive if they don't get replaced, but perhaps in some cases not removing causes some problems with bad poses?

Disable part of commit #28064, this also clears the path on any file giving
problems with file saving, proper fix will come later.

Fix crash in file with image editor that was saved after using scopes.

Fix [#21940] Hotkeys conflict in Edit mode between (fill, beauty fill) and (make/clear F-gon)

Removed make/clear f-gon hotkeys, rarely used and people who want them can bind it
themselves anyway.

Fix [#21756] Texture paint "quick edit" sending wrong path on unsaved scenes

* Made it use the temp directory in user preferences when the .blend file hasn't been saved yet
* Made bmain->name (wrapped as bpy.data.filename) contain an empty string when
there's no .B25.blend and no file saved, rather than "<memory2>".

This is a good candidate for consistent file path api, retrieving temp dirs / project-
specific temp dirs / etc...

Modes are now toggled on using operators on load if the file was saved in
that mode. This ensures proper initialization happens like creating the
cursor or building an acceleration structure. It also means edit and
particle mode are now saveable.

Not sure yet if this is a good feature, though personally I like being able
to load my exact state again after saving, but maybe entering edit mode is
too slow in some cases? It's easy to make it work only for the sculpt/paint
modes again if wanted.

This fixes bug #21004 about a missing sculpt cursor on load.

Revert a crappy line from revision 28060.

Fix [#21677] mouse dragging the translated object doesn't release the object
after a while

Drag code was inadvertently changing the eventstate->type, which isn't
necessary. Patch #21723 by Anthony Edlin fixes this. Thanks!

more functions to stubs.c

Clarify tooltip for 'Align to View' option for adding objects -
It can only align to 3D view when adding the object from a 3d View (eg. shift A),
not the top level add menu.

Fix [#21257] Renders blank images when audio clip is present.

Only render sequencer when there are non-audio strips on the timeline.

[#21931] Rotate Edge CW inverted with CCW

Edge rotate directions were seemingly switched (when looking at geometry with face
normal pointing at view), so flipped them.

Fix [#21760] Snap to Origin doesn't work

Removed the 'Snap selected to origin' operator, it was dysfunctional and other operators
contain better functionality to do the same things.

Brought back:

Node R-key: read scene layers (from temp buffers)
SHIFT+R: read full sample layers.

Fix #20365: new render window does not respect Windows taskbar at top of screen.

Fix #21166: changing image file path does not update texture preview. I've
made it regenerate previews and icons now for this case. Depsgraph for all
datablocks could solve this much nicer..

Fix #20911: automatic bone weights work poorly when vertex lies
exactly on a bone, tweak epsilons to make this work better.

Fix #21545: geometry node front/back incorrectly depended on camera angle, can
actually be implemented simpler now.
