* Change overlay alphas to 33 if not initialized. This should have been
done for 2.67 but better do it now to avoid frustration with overly
transparent overlays. For users that have set this low manually this
will reset the setting to 33 but I think it's less irritating than users
who unwillingly had the setting to 1 and saw nothing when activating the
overlay.
* Allow overlay alpha to be zero as well
* Reset old, now obsolete BRUSH_FIXED flag for brushes that still use
this. I am doing this here to avoid patching hell when the paint brush
is merged, since it's not possible to know the merged version
beforehand, and this flag will be used.
- IsectLLPt2Df
- isect_point_quad_uv_v2
- isect_point_face_uv_v2
These are obsoleted by resolve_tri_uv, resolve_quad_uv
also add attributes for unused function results for some math functions.
the space stroke would be repeated on unneeded subpixel precision. Since
this is not really useful, enforce spacing to be at least one pixel.
This makes small brushes quite more responsive.
Couple of RNA callbacks would imply scene update routines
to trigger. This works fine for until some objects does have
drivers.
If some object does have driver, it'll try to lock GIL
when evaluating this driver, and GIL is already locked by
a python API, which causes deadlock.
For now made it so RNA callbacks doesn't do threaded update.
This is not so much nice, especially since Cycles might
use the same API for motion blur, but for now don't see
better way to solve the deadlock.
Instead of allocating scheduler and starting threads
on every object_update call make it so scheduler is
global and threads are always ready to run.
This was we could avoid quite hacky thing which is
counting how much objects need to be updated before
starting threaded update.
It'll also allow using the same scheduler to do all
sorts of tasks, not only objects update in the same
scheduler. This is nice from load balancing point of
view.
Couple of changes were needed to be done in task
scheduler itself:
- Free tas before sending notifier.
- Free TaskThread structures outside from thread.
This is needed to make it possible use begin/end
threaded malloc from the main thread before/after
running the pool. Without this change it was possible
that allocation will switch to non-thread mode while
thread is freeing the task.
This required storing TaskThread array in Scheduler,
but it's not so much bad actually, since it also
reduces memory overhead caused by per-thread allocation.
This commit fixes two different issues, which were caused by
how weights are being calculated for relative shapekeys.
Weights for key block used to saved in KeyBlock DNA structure,
which lead to situations when different objects could start
writing to the same weights array if they're sharing the same
key datablock.
Solved this in a way so weights are never stored in KeyBlock
and being passed to shapekeys routines as an array of pointers.
This way weights are still computed run-time (meaning they're
calculated before shapekey evaluation and freed afterwards).
This required some changes to GameEngine as well, to make it
never cache weights in the key blocks.
Another aspect of this commit makes it so weight for a given
vertex group is only computed once. So if multiple key blocks
are using the same influence vertex group, they'll share the
same exact weights array. This gave around 1.7x speedup in
test chinchilla file which is close enough to if we've been
caching weights permanently in DNA (test machine is dual-code
4 threads laptop).
Some further speed is optimization possible, but it could be
done later as well.
Thanks Brecht for idea of how the things might be solved in
really clear way.
* Added a node to convert a temperature in Kelvin to an RGB color. This can be used e.g. for lights, to easily find the right color temperature.
= Some common temperatures =
Candle light: 1500 Kelvin
Sunset/Sunrise: 1850 Kelvin
Studio lamps: 3200 Kelvin
Horizon daylight: 5000 Kelvin

Thanks to Philipp Oeser (lichtwerk), who essentially contributed to this with a patch! :)
This is part of my GSoC 2013 project. SVN merge of r57424, r57487, r57507, r57525, r58253 and r58774
* Added a Ray Depth output to the Light Path node, which gives the user access to the current bounce.
This can be used to limit the maximum ray bounce on a per shader basis. Another use case is to restrict light influence with this, to have a lamp only contribute to the direct lighting.

This is part of my GSoC 2013 project. SVN merge of r58091 and r58772 from soc-2013-dingto.
* Code cleanup to avoid duplicated enum code.
* Added a third type for conversion next to Point and Vector: Normal. This is basically the same result as with the Vector type, but normalizes the vector at the end.
Thanks to Brecht for code review!
Clean up inconsistencies in the libmv C API:
- All type identifiers are libmv_TypeName
- All function identifiers libmv_functionName
- Prefer libmv_nounVerb function names (e.g. libmv_featuresDestroy)
- Match Blender code formatting rather than Google
- Spelling corrections

actually just point to existing defined stack values. To make the link check work, set the socket->link pointer if internal node connections exist, this works for both muted and reroute nodes.
necessary.
Problem was/is that the nodes can set the 'type' property, but in order to actually change the data type they would also need to update the typeinfo pointer (and idname), which is strongly discouraged.
Solution is to just replace the input/output sockets of the reroute node with new sockets of the desired type and port all links over.
This significantly lowers the position of outliner_draw_tree_element in profiler
and partially fixes [#36260] (2,300 Objects Makes Blender Unresponsive)
