LANPR: Move main panel to render tab

Merge branch 'soc-2019-outliner' of git.blender.org:blender into soc-2019-outliner

Outliner: Sync selection state on sync selection toggle

When turning on synced selection, sync the selection. Previously
this required clicking in the outliner or doing a 3D view selection
operation.

Merge branch 'master' into soc-2019-outliner

Outliner: Don't adjust horizontal scroll on show active

The show active operator tried to scroll the outliner
horizontally to show the active object. On wide outliners this
caused a jittery redraw on mousemove. When the outliner
was more narrow, repeating the operation also caused
unexpected jittery redraws.

Outliner: Fix TreeStore loading in textbutton edit mode

Fixes incorrectly added the TSE_ACTIVE flag field after TSE_SELECTED
because it logically made more sense there. Old files were loading
with each tree element in textbutton edit mode. This addresses that
and other issues with mismatches on TreeStoreElem flags.

Use some C++ features where useful

Also correct include guards.

Initially move XR files to GHOST and compile in C++

Merge branch 'master' into soc-2019-openxr

Outliner: Versioning for active element theme change

It doesn't have a version bump condition currently to always apply
the theme during the summer of code

[Fast import/export] Changed to use C style output for OBJ

Merge branch 'master' into soc-2019-outliner

Making OpenVDB compile.

improved particle attribute handling

utilities to create a range before/after another

SmallVector: Append N Times

disabled offset based fallback in rotation calculation

it caused unwanted sudden rotation changes

Cloth: don't use current method of adding verts

The current method will not work after collapse edges is implemented, it might cause lose of information thus simulation would not be accurate.
Need to convert ClothVertex to be an array instead, and work from there.

Cycles: VDB lookup transformation is now entirely derived from Blender input, no more lookups into VDB world transform. This fixes some VDB files that rendered incorrectly.

Cycles: fixed Linux build with gcc
