Blender Git Commits

WIP commit, basically introducing a few things here:

* highlighted vs active widget.

Active widget takes all input and basically highjacks drawing of all
other widgets in the widgetmap.

* operator names for widgets. Now widgets will spawn operators based on
names that are passed on them. They will also modify a named property of
the operator and pass it on, after which operator can process it.

quiet warning

Fix compilation error -- backported change relied on the regular development changes

Buildbot: Rename testbuild branch to experimental-build and put the builds to dedicated folder

Better fix for T42139

Noise function's significant bits are up to 31st bit. This should now
give the same visual result as before, minus the stripes.

Issue pointed out by Anthony Edlin, thanks!

Fix for No Sudo option in install_deps.sh (typo in docs)

Bugfix T42225: Python - GreasePencil.active incorrectly accepts GreasePencil type instead of GPencilLayer

Manipulator:

* Fix error in plane manipulator handling.
* Don't show manipulator widgets on paint modes.

Fix T42206: RenderLayers popup crashed when clicked while rendering

Fix T42005: Reset py-handlers could crash

Wasn't acquiring the GIL.

Fix previous stupid commit about bvh precision! What we want here is ray radius, not
bvh creation epsilon.

BVHTree Mesh helpers: Add support for raycasting against verts/edges.

iNote: pure theoritical code, not tested at all yet!

Only detect active widget on mousemoves. Now handler operates on
mouseclick (bound to change)

Fix T42064: Directional blur uses wrong sampler

Now use linear one, nearest is far too doggy.

Fix T42160: CUDA error: ILLEGAL_ADDRESS in cuCtxSynchronize()

This is so-called GPU limitation boundary hit, told compiler to NOT include
volume bound function, otherwise some real weird things used to happen.

We actually might want to do the same for CPU, inlining everything is not
the way to get fastest code.

Fix T42198: Linked lines only work with linked objects.

The reported issue was caused by a backward incompatibility due to careless
code changes made when per-material Freestyle line colors were introduced
in rB7915d7277ac8c605f016f30f943080556244fb59. In 2.71 line style
Material color/alpha/thickness modifiers was retrieving alpha transparency
from Material.alpha, whereas in 2.72 Material.line_color[3] was referenced.

The present fix reverts the aforementioned code changes.

This issue is a regression from 2.71, so the fix is appropriate for inclusion in
the 2.72a release.

Merge branch 'master' into wiggly-widgets

Ring widgets:

Add a clipping style, just like manipulator

Undo previous changes to sound.

The sound system really needs better design for the sequencer and
patching it up now won't really help us in the long run.

Also the sequencer kept leaking file descriptors when preserving
the audio handlles on undo making the branch unusable on mac and
windows.

It's almost certain patching over this will lead to more trouble, better
handle it separately and keep the system working for now.

Kept threaded loading of waveforms since we control the file input
directly there and leads to nice speedup, but we still clear the whole
sound + the waveform on undo, which is pretty bad.
