Fix: OSL shader used both the wrong and the unadjusted type of roughness

Merge branch 'master' into soc-2018-hair-shader

Week 9 merge: no issues

Lift upper bounds of roughness/radial roughness

Fix error when render

The v3d pointer is null when renders, so need to be checked before use it.

Fix errors and changes after merge

Move Vertex Opacity from Tolsettings to View3D

The vertex opacity is a parameter of the view and not of toolsettings as it was defined before.

With this commit we moved the last parameter to control the view look to the right place.

Verify View3D is vailable before using it

This variable is not loaded when render.

Eevee: LightCache: Add Autobake property

This also add partial probe update per type (only update cubemap if needed)
but it seems to be broken by some double update tagging in the depsgraph.

New Main switch at view level for Onion Skin

The switch is on top of GP datablock onion switch and allows to show/hide all datablocks in the view.

Move Edit LInes and Multi Edit LInes switch at View level

This overlay must be by view, not by object.

Also changed the name to "gpencil_*" to some grease pencil paper to keep name consistency.

UI: Define a Header Text for Overlay Panel

fluid guiding overhaul

- fluid guiding now has a separate cache. velocities from guiding
objects can be baked into this cache
- alternatively, another another (baked) fluid domain can be set as the
parent. its velocities will then used for the guiding effect (e.g. use
smoke sim to guide liquid sim)
- minor other updates: refactored manta-script exporter, fixed liquid
leak (fractions completely disabled now), naming cleanups, fix for
smoke resume bake (was missing velocity reload)

Eevee: LightCache: Add auto update when lightprobe are being modified

One draw back is that there is a significant overhead caused by creating
the batches for the new depsgraph. Caching the depsgraph between subsequent
update is not possible right now because we cannot update it. This is to be
adressed in the future.

There is no option to disable auto update right now.

Try to fix the rim problem when the image ends outside view

The rim is disabled if the image to rim extends beyond the borders.

Improve Blur qualitty when the zoom factor changes

Now the number of pixels to blur depend of the pixel size and not as fix values as before.

Fix animation path typo error

This error made impossible animate modifiers.

UI: Reorganize Overlay panel

The separated panel for Paper and Options has been replaced by an unique panel, because two panels display too much empty space between them and make easier the maintenance.

Following how works other Blender panels, the paper options are hiddden when the paper is disabled, only required parameters are displayed.

We keep Onion switch here because is still pending the decission to use a general switch (mesh and GP) or keep separated switches.
