Greasepencil icons

Note this comes from the greasepencil-object branch, and are merged to help
preventing future merge conflicts.

Also, I renamed the icons for consistency sake. So when this is merged in 2.8
other areas of the code will need to change.

Cleanup: some ED_view3d functions used uppercase D

Merge branch 'master' into blender2.8

Fix Cycles assert when resizing rendererd viewport.

Cycles: change material output displacement to vector.

Previously only scalar displacement along the normal was supported,
now displacement can go in any direction. For backwards compatibility,
a Displacement node will be automatically inserted in existing files.

This will make it possible to support vector displacement maps in the
future. It's already possible to use them to some extent, but requires
a manual shader node setup. For tangent space maps the right tangent
may also not be available yet, depends on the map.

Cycles: add Displacement node.

This converts object space height to world space displacement, to be
linked to the new vector displacement material output.
