Fixed inconsisancy causing calling direct_emission twice from merge.

Cycles: Fix uniform cone sampling

This code is currently only used for the Glossy Toon BSDF, but it's a generic
building block that might be used for other things in the future.

To see why the current code does not give a uniform distribution, consider that
it chooses both angles uniformly, but the smaller the angle from the center of
the cone is, the smaller the differential solid angle is (similar to how
sampling disks by choosing radius and phi uniformly does not work).

Reloaded commit.

UI: Remove extra separator in some cases

Fix missing animation decorators for pointer buttons

Also, remove manually placed decorator for vertex groups in modifiers. This was
only needed because of this bug, and the layout was slightly misaligned.

UI: Set modifier panel expansion on every redraw

This will fix situations where the modifier epansion was set elsewhere
besides the UI, like from the python console, solving the drawing part
of T77502.

Also adds update tags to the show_expanded property, which means
the properties window redraws when the property changes.

Sculpt: Face Set Edit Operator

This operator performs an edit operation in the active face set defined
by the cursor position and updates the visibility. For now, it has a
Grow and Shrink operations, similar to Select More/Less in edit mode or
to the mask filter Grow/Shrink modes. More operations can be added in
the future.

In multires, this updates the visibility of an entire face from the base
mesh at once, which makes it very convenient to edit the visible area
without manipulating the face set directly.

Sculpt: Pose Squash and Stretch deform mode

This implements squash and stretch as a deform mode for the Pose Brush.
It is similar to scale, but it applies different scale values in different
axis. To achieve this, the pivot local space of the transform needs to
be aligned to the segment when using this deform mode to apply the scale
in the correct direction.
