Fix T38359: Not a bug, but better to grey out Material selector of particles when using Object or Group render type (since we always use duplicated objects' materials in this case!).

Fix T38356: Crash when UIList.filter_items returns too few items.

Change tooltip text for Vertex Group in Bevel Modifier.

Reflects previous commit that now allows this group to
control edge bevels too.

Bevel modifier can use vertex groups for edge bevel now.

Until now, the "vertex group" limit method in the modifier
only worked for "vertex only" bevels. With this change,
edges with both ends in a vertex group will be beveled
in the non-"vertex only" case.
Also changed the test for being in a vertex group from
"any nonzero weight" to "weight >= 0.5". This is because
cascaded bevels on disjoint vertex groups did not give
disjoint bevels, because weight interpolation would give
non-zero weights to newly created vertices in earlier bevels.
Chose 0.5 because that won't result from interpolation, but
still allows some dilution (e.g., cascaded bevels on the
same vertex group).

Add convinient access to full bitangent for loops (some export formats like FBX expect full bitangents, better to compute them in C than in python...)

Fix T38347: adding object visibility keyframes in the outliner groups and
libraries view not working.

This was disabled in the operator, there may have been a reason for this at
some point, but I can't see any reason to disallow it in the current code or
find a good reason why it was done in the commit logs.

Make multisegment bevel profiles even for all parameters.

The method for calculating points on the profile for non-circles
and non-lines meant that the segments making up an edge had
uneven widths.
Use a numeric search technique to find superellipse evaluation
points that lead to equal-sized chords across the profile.
Also calculate the actual profile points sooner, so that they
don't have to be recalculated again and again.
This also sets up for a possible later feature of arbitrary
profile shapes, set by user.

Cycles Standalone: Add a help message, which appears when pressing the "h" key.

This is very basic for now, but can be extended with more info (available devices for example) later.

Thanks to Bastien and Sergey for some help with the glRect coordinates stuff.

Fix currently harmless issue with converting ImBuf from sequencer space

Fix compilation error caused by 67f1fd2

Did one tried building blender before commit even?

game engine: implement hitMaterial for collision and ray sensors

Reviewed By: moguri, kupoman

Differential Revision: https://developer.blender.org/D167

Add support for new "bl_category" member (new panels "tabs" system).

Fix T38150: implementation mismatch in bmesh python

Hopefully this time all mismatches are fixed (quickly checked the whole BMesh API files,
found a few others in addition to those reported in T38150).

Make Tab Divider interopolate between the region background and tab outline.

Previously the divider was using the region background and the region text, leading to bad outlines with custom themes. This makes the outline behave more expectedly and allows better control.

Fix T38337: Crash when calling to_mesh() on a Curve object after clearing its parent

This is rather a workaround which only works because curve evaluation is only called
for a temporary object. Not a big deal if we'll skip path creation for such objects.

Still would need to think of general solution.

Fix T36165: blender internal HDR textures with negative values got clamped.

For example for vector displacement, you may have an EXR texture that has
negative colors values. Blender clamps these by default, now the Colors panel
for textures has a Clamp option to disable this clamping.

This option affects all texture types and is enabled by default, you need
to disable it if you want negative values to have an influence.

Patch by Fredrik Hansson with modifications by me.

Fix T37302: cycles slow hair export with many hairs, especially on Windows.

Fix T37685: automatic weights affected by face masking outside weight paint mode.

Only when in weight paint mode should it check the selected vertices and faces,
in object mode it should just affect the entire mesh.

Cleanup: int/short to bool in BKE_cdderivedmesh.h functions (and TRUE/FALSE to true/false in code using them).

Fix crash when changing space type to 3D space when having multiple windows

it is possible that different windows shares scene but displays different
layers. And it's also possible that different areas in the same window will
show different layers.

First case was violated in `dag_current_scene_layers()` which only checked
scene layers only once and if multiple windows shares the same scene only
one window was handled. Now made it so layers from all windows will be
squashed together into a single `DagSceneLayer`. This mainly solves issue
with `DAG_on_visible_update()` which didn't work reliable with multiple
open windows.

Second case required call of `DAG_on_visible_update()` when changing space
are type.

This commit slows things a bit actually because `dag_current_scene_layers()`
is actually called on every main WM loop iteration. It is possible to speed
some logic up perhaps. Not sure it's so much critical to do now because there
are unlikely to be more than few windows open anyway.

Will rather think of skipping all that flushing things if no objects are
tagged for update actually.
