Merge branch 'blender2.8' into greasepencil-object

Only align to view by default Monkey GP object

The blank grease pencil object must be aligned to axis by default.

Add a warning in annotations if active object is GP

Now the annotations is not working with grease pencil object selected and we need inform the user.

We need find a better solution for this, but at least we have a notification and not something that looks a bug, but a not supported function.

New grease pencil transform icons

Added init code for default LANPR values. Fixed render and scene panels to accept LANPR engine.

Change icon names to define custom grease pencil icons

The standard icons for these operators don't fit in the grease pencil use and it's better to have icons more designed for grease pencil strokes.

Fix: Ensure that LANPR panel is only enabled when that engine is enabled

- Fixed incorrect COMPAT_ENGINES define

- Removed poll() callback that was preventing the COMPAT_ENGINES
set from working

- Have panel opened by default (since it doesn't need to stay collapsed
when other engines are active anymore)

Example commit for fixing panel visibility when LANPR is enabled

Following the examples here (for the Scene/KeyingSet settings),
all general non-engine-specific panels should include "BLENDER_LANPR"
in the COMPAT_ENGINES set.

Automatically refresh viewport when changing LANPR settings

Use the messagebus struct-subscription methods here (as used for EEVEE settings)
so that changing rendering methods or other settings immediately refreshes
the viewport instead of requiring the user to click on the viewport to force
a redraw.

Fix compiler warnings (use 0 in enums for no icon, not NULL) + whitespace (mixed tabs/spaces)
