Revised external multires file saving. Now it is more manual in that you
have to specify where to save it, like an image file, but still saved at
the same time as the .blend. It would ideally be automatic, but this is
difficult to implement, so for now this should at least be more reliable.
This is still a bit dodgy, the issue of accessing scene data from nodes needs to be solved better, but this at least fixes it up to previous capabilities, and prevents writing any data to scene/objects either.
* Sound strips now respect metastrips for muting. That means they
are muted if the metastrip is muted, and don't play when located
outside of the current metastrip.
* Operators now use notifiers instead of redraw tagging, added a
separate notifier for selection as well, but that is not used to
do less redraws yet.
Useful when openAL is not setup properly (*cough* pulseaudio *cough) and prevents startup.
This doesn't actually affect the userpref option, so you can set it to whatever you want, save userprefs and restart.
* Don't allow adding/removing multires levels in editmode.
* Customdata code for swapping mdisps restored.
* Fix inflate brush crashing with multires.
* Smooth and layer brush don't work yet with multires, but at
least avoids crashing now.
* Fix threading issue with flatten brush.
* Make partial update work again for faster editing.
* Draw parents over children again, nicer for editing.
* Fix crash with remove tools & showing child particles.
* Fix children not disappearing always when setting to None.
* Fix wrong normal for last point in child path.
* Fix a python error in the hair dynamics panel.
* Multithread parts of multires and subsurf. Only loops working on
face grid data and do no memory allocation have been multithreaded,
others would be more complicated.
* Force some CCGSubsurf functions to be inlined, gives a small overall
speedup in subsurf code.
* Fix sculpting not working correct with transformed objects.
* Fix a few cases of "spikes" on lower level multires levels. There's
still cases where it happens, usually on boundary cornders. The
problem is that in such cases the limit surfaces can be very different
from the low res surface, so the tangent space is very different too..
* Fix crash deleting multires higher levels with level set to 0.
* Fix crashes that happened sometimes when adding faces in editmode.
After testing and feedback, I've decided to slightly modify the way color
management works internally. While the previous method worked well for
rendering, was a smaller transition and had some advantages over this
new method, it was a bit more ambiguous, and was making things difficult
for other areas such as compositing.
This implementation now considers all color data (with only a couple of
exceptions such as brush colors) to be stored in linear RGB color space,
rather than sRGB as previously. This brings it in line with Nuke, which also
operates this way, quite successfully. Color swatches, pickers, color ramp
display are now gamma corrected to display gamma so you can see what
you're doing, but the numbers themselves are considered linear. This
makes understanding blending modes more clear (a 0.5 value on overlay
will not change the result now) as well as making color swatches act more
predictably in the compositor, however bringing over color values from
applications like photoshop or gimp, that operate in a gamma space,
will give identical results.
This commit will convert over existing files saved by earlier 2.5 versions to
work generally the same, though there may be some slight differences with
things like textures. Now that we're set on changing other areas of shading,
this won't be too disruptive overall.
I've made a diagram explaining the pipeline here:

and some docs here:

Brought back default effect fading: (adding a wipe effect makes it
wipe by default for the length of the strip)
First round in upgrading IPOs from older versions. (works for non-IPO
case now and sets at least the new "default effect fade"-flag)
Still non-working for old IPOs, since Sequence-Strips aren't real IDs!
And: non-frame-lock case should stretch the FCurve to the right length!
* Set default particleedit selection mode in add scene (TODO: not yet changed in the default blend)
* Corrected names for particleedit selection mode in RNA, added icons
* Added occlude geometry flag to view3d RNA
* Converted particleedit buttons to uiItems in view3d header
* Now support a Surface mode next to the existing Volume mode. This binds
the mesh to the cage mesh surface rather than it's volume.
* Implemented reusing the bone heat weighting code.
* Advantage is that it works for cage meshes that are not volumes and that
binding is much faster.
* Weak point is that disconnected components of a mesh are not guaranteed
to stick together (same problem exists with bone heat weighting).
* Bind weights could still be compressed better to use less memory.

* Increased the number of Armature and Bone Layers from 16 to 32. Please note that older versions of Blender may not correctly resolve the layers that bones are on when loading new files.
* Newly added objects are now made by default to allow locking of 4-component rotations using 4 separate locks (i.e. one by component) instead of requiring the obscure 'W' toggle (renamed '4L' now) to be enabled first. The objects in the default scene need modifying manually though.
This patch, by Elia Sarti (vekoon), simply adds the possibility to specify the final array component of the RNA path in the path itself,
e.g. using location[0] or location["x"] or even location.x,
instead of specifying this using an "array_index"
This should be easier for users to understand the driver system. The array-indices have been kept (but hidden from the UI under standard situations) since they are theoretically a tad faster than the in-path lookups still, and are easier for internal-tools to set for now...
- Drivers on added to the 'armature' datablock (i.e. keyframing some settings for a "Bone" as opposed to "PoseBone") now evaluate correctly. Added proper recalcs for this case too.
- Also fixed some memory leaks and loading problems I encountered with the test file provided. After having problems loading the test file, I ended up reproducing and finding the error.
* This is experimental, the file format may change still!
* Helps reduce memory usage, keeps .blend files smaller, and makes
saving quicker when not editing multires.
* This is implemented at the customdata level, currently only the
multires displacements can be stored externally.
ToDo
* Better integration with object duplication/removal/..
* Memory is not yet freed when exiting sculpt mode.
* Loading only lower levels is not supported yet.
* Displacement coordinates are now stored differently, as a grid per
face corner. This means there is duplication of coordinates, especially
at low subdivision levels, but the simpler implementation justifies it
I think.
* ToDo: conversion of existing multires files (2.4x or 2.5x), loading them
may even crash now.
* Editmode preservation/interpolation code also has not been updated yet.
* Multires now works on the CCGDerivedMesh grids instead of CDDerivedMesh,
which should be more memory efficient.
* There are still bad memory peaks (if you're using 32bit) when subdividing
or propagating displacements. Though at least there should be no huge
memory blocks allocated, which windows is now to have trouble with.
* Still found some weird spike artifacts at lower multires levels, some also
happening before this commit. Perhaps computation of tangents needs to be
tweaked more.
* Multires modifier now has viewport, sculpt and render levels. Also the
levels have been made consistent with subsurf, previously the same level
of subdivision was one less for multires.
* Both multires and subsurf modifier now can have their subdivision level
set to 0 for no subdivision.
* PBVH can now be created contain both from face grids or standard
meshes. The former is much quicker to build for high res meshes.
* Moved some drawing code into pbvh (mostly for the frustum test).
* Moved ray intersection code into pbvh.
* GPU buffers also can be built from either mesh or grids now.
* Updated sculpt code to work with this. The ugly part is that there
is now a macro for iterating over vertices, to handle both cases,
and some duplicated code for e.g. undo.
* Smooth brush does not work yet with grids.
* Now uses the CCG DerivedMesh also in object mode, used to be edit mode only.
* Create CD_ORIGINDEX layer on demand, to save memory.
* Removed ss_to_cdderivedmesh function, and instead create ccgdm and then
convert that to cddm, to avoid code duplication.
* Added and implement DerivedMesh interface functions to obtain face grids.
* Store edge/face flags more memory efficient.
* Export CCGDerivedMesh struct in BKE_subsurf.h
The Animation System now respects the Transform Locks too (i.e. lock x-location, etc.) when writing settings. This means that it is no longer necessary to set up "constant drivers" to make sure some values don't get accidentally animated.
Internally, added a new callback for properties in RNA, which is responsible for checking if the item at some array-index is editable. This needs to be manually called for each place which uses rna to set settings for arrays (see the code changes in anim_sys.c for changes how to do this; the same thing needs to be done in the UI code too, and probably in py-api too)
* Fixed a few compile warnings for scons+mingw
* Driver variables are now added with the ID-type set to ID_OB (objects) by default since this is more convenient
