By calling `tessellate()` from the mesh manager in Cycles we can do pre/post
processing or even threaded tessellation without concerning client side code
with the details.
This way OpenCL devices can also benefit from a smaller memory footprint, when using e.g. bumpmaps (greyscale, 1 channel).
Additional target for my GSoC 2016.
When updating the max values under stiffness scaling, they clip at the normal stiffness values
as expected, however when updating stiffness values, you could set them higher than the max
values, and the max values weren't updated accordingly. As the stiffness scaling computes using
the absolute difference between the max values and the stiffness values, you got higher
stiffnesses in scaled areas even though your max is actually lower than the normal stiffness.
This diff fixes that behaviour, by updating the max values to be equal to the stiffness whenever
you set a higher stiffness than the max value.
Also, I have initialized the max values to the same as the stiffnesses, as they were previously
just set to zero, and caused the same problem described above.

Node tree update calls in the middle of a socket loop are dangerous, they can change sockets
on group nodes and link instances in particular. Updates should only happen after the operator
has finished.
Simply removed the extra convenience check for validity now. Worst case an invalid (red) link
is created which can be removed by the user as well and should simply be ignored by node systems.
The update system in nodes needs a complete rewrite to handle complex cases like this, where an
operator may need to react to changes during its execution.
GPencil conversion would just always run for file version 2.77.3. This wasn't an issue in master, but possibly for other branches that used the 2.77.3 block.
Wasn't aware that you have to add the asterisk for pointers either, this is kinda weird. Anyway, it's running correctly now.
New dependency graph puts materials to the graph in order to deal with animation
assigned to them and things like that. This leads us to a requirement to update
relations when slots changes.
This fixes: T49075 Assignment of a keyframed material using the frame_change_pre handler
doesn't update the keyframe using the new dependency graph
This is mainly required for the new dependency graph where non-object
datablocks are a part of dependency graph.
This solves issue when making mesh shared by multiple objects a single
user one.
Now we have the 4 component ones first (float4, byte4, half4) followed by the 1 component ones (float, byte, half).
Makes code a bit more consistent and also reduces code a bit when enabling half support on GPU in next commit.
This also exposed a typo in half CPU images for 3D textures, which wasn't used yet, but good to have that one fixed anyway.
Point cache read code contains checks designed to prevent it reading
stale data when the relevant simulation code should instead compute
the next frame from the previous one. However in some situations like
motion blur subframes the simulation can't possibly do it and just
exits. This causes completely incorrect motion blur at or after the
last cached frame.
To fix, add a parameter that tells the cache code whether it should
apply the checks and exit, or read what it can even if stale (true
means exactly same as old behavior).
Doing this in cache rather than clamping the frame number better in
the caller lets it handle the case of incomplete cache that stops
before the official last frame.

Using unit tests is a wrong way to control static behavior of the
application. They should only be used for checking dynamic behavior,
all the rest is easily controllable at compile time.
Doing tests at ocmpile time are actually more robust approach since
we don't have strict policy of runnign unit tests before accepting
any change.
Proper alignment control is coming shortly.
This reverts commit 7c3a06c34918567e6b0ab67bded60725ff63073b.
Since the optimal values depend on the device used, this option doesn't make much sense in the XML.
Therefore, it's now specified via the command line, just like the device itself.
it is incorrect to set ROOT_DIR and then call find_package.
If something is expected to be in a given location use hardcoded
locations (for the precompiled libraries). Otherwise just use
find_package() and let users to set ROOT_DIT when it is required.
The first character of the ID type was used to tag IDs for updates which
is weak since different IDs can have the same first character (for
example meshes, materials and metaballs), causing unnecessary updates of
unrelated IDs.
Now we use a unique index per ID type to tag for updates, unifying IDs
arrays indexing along the way.
