Cleanup: remove some G.main usages.

Merge branch 'master' into blender2.8

Cleanup: trailing space in RNA

Cleanup: style

UI: initial support for parent panels in popovers

Currently this just includes the panels, no support for collapsing yet.

Extrude operator for hair bundles.

Cleanup: Remove unused line

Add a new User Prefs parameter to control GP multisample AA

For general use of Viewport the multisample AA is not required and can produce errors in selection, but for grease pencil the AA is required all the time to get smooth lines, so a new parameter has been added to User Prefs screen to define this value.

If we use the same value for both AA (grease pencil and Viewport), the viewport would be intefered by grease pencil settings.

The new value is below Viewport Samples.

By default the value was set to 4 samples.

This changes was done as result of requirement of grease pencil development team artists.

WIP: Add parameter to multisample

RNA: revert object mode re-order

This was done so numbered shortcuts made sense.
Now order matches master.

GHOST/X11: Print the keycode w/ debug enabled

Workbench: Fix incident vector calculation.

This fixes specular in perspective view.

Workbench: Fix xray normal not being normalized.

Workbench: Matcaps: Fix matcap under perspective.

This fixes the problem that matcaps have when using a very larg FOV in
perspective view.

This was because it was stupidly using the normal direction which can not
aligned with the view vector under perspective.

So to workaround this problem we don't use the normal as is, but compute
how much it's facing the camera.

This changes how matcaps looks in perspective because they now always use
the full range of the matcap (which is expected).

GHOST/X11: Correct non-latin kb workaround case

Harmless since this is always enabled,
only do this for easier troubleshooting when disabling the define.

GHOST/X11: support accessing physical keycodes

This means we can check keys such as tilde in a generic way.
