Workbench: normal packing

Normal packing. The sign is stored in the A of the color buffer.
if the A == 1.0 the normal should be inverted. before use.

The reason is that packing has more precision for frontfaces, than for
backfaces

UI: shrink operator menu hold triangle a little

UI: workaround for text & icon alignment

Blender's icons weren't written to draw different sizes.
For now ifdef in a hack to show toolbar icons larger.

UI: icon-only hold popup uses region alignment

Gives nicer tool popups for icon only buttons.

WIP: Mega Refactor to replace Palettes with Materials - 1

Fix selection with image planes

Multi-Pose: Port POSE_OT_select_mirror

WM: Add GHOST lazy init for background mode.

This allows for background rendering with EEVEE and other opengl render
engine.

I've only tested it on Linux for the moment so I can't say about other
platforms.

We do lazy init because we cannot assume we will need Ghost for rendering
before having parsed all arguments and we cannot know if a script will
trigger rendering. This is also because it currently does not work without
any display server (blender will crash).

GHOST: Fix missing glXCreatePbuffer initialisation.

For some reason this happened if no windows are created before creating an
offscreen context.

GHOST: GLX: Remove old version check.

EEVEE: UI: Add missing separator.

EEVEE: UI: Merge the custom parallax checkbox with the panel title.

Merge branch 'master' into blender2.8

UI: optionally pass icon size to widget_draw_icon

No functional changes.

Depsgraph: Don;t use copy actions flag

Is useless without main.

Merge branch 'master' into blender2.8

Library: Add assert to catch unsupported copy flags combination

Thanks Bastien for review!

Workbench: make normal packing optional

Merge remote-tracking branch 'origin/blender2.8' into temp-modifier-rm-cddm
