This gives around 30% of speedup for gaussian blur node.
Pretty much straightforward implementation inside the node
itself, but needed to implement some additional things:
- Aligned malloc. It's needed to load data onto SSE registers
faster. based on the aligned_malloc() from Libmv with
some additional trickery going on to support arbitrary
alignment (this magic is needed because of MemHead).
In the practice only 16bit alignment is supported because
of the lack of aligned malloc with arbitrary alignment
for OSX. Not a bit deal for now because we need 16 bytes
alignment at this moment only. Could be tweaked further
later.
- Memory buffers in compositor are now aligned to 16 bytes.
Should be harmless for non-SSE cases too. just mentioning.

This means packed images and movies are now supported when using OSL
backend for material shading.
Uses special file name to distinguish whether image is builtin or not.
This part might become a bit smarted or optimized a bit, but it's good
enough with this implementation already.
With very small meshes or very small bevel amounts, the bevel
profile would be flat even if a round one was requested.
Problem was that the code was checking the length of a cross
product for closeness to zero to test coplanarity. Needed
to normalize things before making that test to account for scale.
Suggestion by Andy Davies (metalliandy) to conform with industry standard (custom cage is something else apparently)
Note: this is the last bake related commit I plan for 2.71/rc (unless
everyone agrees that we could squeeze in D546 - custom UVs, which would
be really nice to add for 2.71 scripters)
Note 2: I'll update the wiki docs shortly
slightly outside the mesh.
Reported by Thomas Beck on irc. Issue here is that the mesh bounding box
changes as we are transforming the vertices. Solution is to collide
against the initial bounding box. Unfortunately the snapping functions
are made in a way that a lot of code needed to be tweaked here, but the
change should be straightforward and harmless (famous last words, I
know).
Ideally we might want to even increase the size of the bounding box a
little (as seen in screen space) to allow snapping even in cases where,
cursor is slightly outside the bounding box, but since this is not so
straightforward to do for all cases, at least for me, leaving this as
a TODO.
In the future i'd rather have this reported to an
upstream instead of adding local changes. It's really
easy to override this changes if patchset is not added
and this is to be fixed in upstream. Also the function
was never used so it was rather totally harmless warning
for us.
There is a new option to select whether you want to use cage or not.
When not using cage the results will be more similar with Blender
Internal, where the inwards rays (trying to hit the highpoly objects)
don't always come from smooth normals. So if the active object has sharp
edges and an EdgeSplit modifier you get bad corners.
This is useful, however, to bake to planes without the need of adding
extra loops around the edges.
When cage is "on" the user can decide on setting a cage extrusion or to
pick a Custom Cage object. The cage extrusion option works in a
duplicated copy of the active object with EdgeSplit modifiers removed to
inforce smooth normals. The custom cage option takes an object with the
same number of faces as the active object (and the same face ordering).
The custom cage now controls the direction and the origin of the
rays casted to the highpoly objects. The direction is a ray from the
point in the cage mesh to the equivalent point to the base mesh. That
means the face normals are entirely ignored when using a cage object.
For developers:
When using an object cage the ray is calculated from the cage mesh to
the base mesh. It uses the barycentric coordinate from the base mesh UV,
so we expect both meshes to have the same primitive ids (which won't be
the case if the cage gets edited in a destructive way).
That fixes T40023 (giving the expected result when 'use_cage' is false).
Thanks for Andy Davies (metalliandy) for the consulting with normal
baking workflow and extensive testing. His 'stress-test' file will be
added later to our svn tests folder. (The file itself is not public yet
since he still has to add testing notes to it).
Many thanks for the reviewers.

This reverts commit da7bdf1b47d4490c1a6f35740a9392cb9b5dd42e.
This broke compilation in OSX and some Linux boxes.
Error: Policy "CMP0043" is not known to this version of CMake
Shall we leave those for after RC (or even 2.71) is out? ;)
!!! ANIMATORS/RIGGERS PLEASE TEST !!!
I've reduced the size of the threshold for the keyframe lookup here. This threshold
determines the minimum time in frames between keyframes (i.e. "how close" to each
other they can get). Making this too small causes problems like T39207, but it seems
that the threshold we've been using makes it impossible to get accurate behaviour on
driver curves with keyframes, when the driver target only moves 2cm (i.e. 0.02 BU).
So far, all of the test cases from T39207 seem to work fine, as well as Caminandes 2
files, and Kenny the Caterpillar. The Kiribati rigs/shots (thanks jpbouza for helping
to check on these!) also seem to be fine.
