Our new guarded allocator implementation has much smaller memory
block size overhead and doesn't have any locks now. So in order
to make fuller track of what's happening in blender and avoid
confusion why certain circumstances reports much less memory than
others we'll now switch to guarded allocator.
This was actually one of the biggest reasons of the confusion in
the recent memory usage investigation. There's still some overhead
is happening due to non-freeing nature of arena allocator but the
things are not nearly as bad as they looked before: memory overhead
is measured in tens of megabytes, not hundreds as it looked before.
Plus with some smarter allocation policy we can almost eliminate this
overhead.
This commit introduces a few ready made effects for the 3D viewport
and OpenGL rendering.
Included effects are Depth of Field, accessible from camera view
and screen space ambient occlusion. Those effects can be turned on and
tweaked from the shading panel in the 3D viewport.
Off screen rendering will use the settings of the current camera.

This feature has been totally broken for a long time. It was added
originally because negative frames were not supported.
Giving simulations (cloth and others) time to settle before animation
starts needs to be solved in a much better and more generic way.
Particle textures always override timing information of particles.
Previously particle times could be scripted, but now these changes are
discarded by the texture evaluation function.
The patch disables texture overriding when no textures are defined, this
way at least some old scripts can keep working.
structs to paint struct (might be useful for vertex paint too in the
future)
Cavity masking now has a curve control. The control will set the amount
of masking for positive cavity ("pointness") or negative cavity
("cavity") with x axis being the amount of cavity and 0.0 = full cavity,
1.0 = full pointness, 0.5 = no cavity and the y axis being the amount of
alpha.
The issue was caused by the fix for T34108, which modified DNA in order to
get a fallback box collision shape. Not sue why it's needed, we can just get
box shape directly, without modifying user's settings.
Using different scenes with 2+ windows broke entirely using undo.
Now keep track of the current windows scene in each undo-file,
and ensure the undo-scene is on a visible window when undo is executed,
switching the scene only when its not in a visible window.
Running this operator and and closing Blender gives this:
Error: Not freed memory blocks: 2
ImBuf_struct len: 2480 0x69ba4f8
imb_addrectImBuf len: 1048576 0x6ccc2d8
Fixed with added call to IMB_freeImBuf in BKE_image_add_from_imbuf.
Could be fixed in the operator instead, but I think the BKE function
is the correct place since the comment says it should take ownership
of the ImBuf.

Error in custom split normals work, non-autosmooth normals != vertex normals!
Loops from flat faces shall take normal of their face, not their vertex.
Tsst...
Titles says everything, just two notes:
* We have to actually transfer plain *normals*, not 'compressed' clnors,
so had to add pre/post process to transfer to make the conversions.
* Also added interpolation and advanced copy/mixing to CD_NORMAL, for same reasons.
This is the core code for it, tools (datatransfer and modifier) will come in next commits).
RNA api is already there, though.
See the code for details, but basically, we define, for each 'smooth fan'
(which is a set of adjacent loops around a same vertex that are smooth, i.e. have a single same normal),
a 'loop normal space' (or lnor space), using auto-computed normal and relevant edges, and store
custom normal as two angular factors inside that space. This allows to have custom normals
'following' deformations of the geometry, and to only save two shorts per loop in new clnor CDLayer.
Normal manipulation (editing, mixing, interpolating, etc.) shall always happen with plain 3D vectors normals,
and be converted back into storage format at the end.
Clnor computation has also been threaded (at least for Mesh case, not for BMesh), since the process can
be rather heavy with high poly meshes.
Also, bumping subversion, and fix mess in 2.70 versioning code.
This is mandatory for incoming custom normal imports from io scripts, because
often geometry here is corrupted, so we need to call mesh.validate() to clean it up.
Issue is, we cannot set custom normals before geometry is clean, so we need to store
temporary plain loop normals in a CD_NORMAL layer, validate, and then set custom normals.
So we need a way to prevent 'temp' lnors to be freed by validate.
Don't scale proxies, same as we do in gooseberry, also for sound synch
give a small window around sound where frame is just pushed forward.
Avoids video jumping in the cases when video renders faster than sound
(yes, weirdly enough it happens sometimes). There might be a few jumps
but results looks smoother here.
This is actually issue with Image datablock, which had obscure Fields settings
but didn't allow to de-interlace the video.
Now added the option to de-interlace Image with Movie input type.
The internal cloth modifier effector weights get replaced temporarily
to make the cloth sim use the particle weight settings instead. But
the particle sim was not putting back the original weights, which can be
non-NULL in case the cloth sim allocated these already. Messy design ...
If user cancels, there's an issue with leftover files.
Instead use a hash to record files that have akready been registered for
generation and skip them if so.
That should guarantee things will go smoothly and when a file exists it
is assumed to be valid.
