Fix error setting origin

The calculation was not right if the object had rotations

Finish polyline session releasing Shift

For artist is better cancel polyline drawing session releasing the shift key instead to press Esc or Enter.

Now, to draw polylines keep shift pressed and finish releasing this key.

added the alpha along with rgb in .ply exporter in vpaint

WIP: Boundbox for GP object

This is the first implementation but cannot test because Eevee not support bounding box yet.

Fix redraw glitches with popups overlapping topbar

UI: Enable set origin for GPENCIL type

Use tabs to list workspaces in topbar

Did some additional changes to make tabs align properly and look good.

Merge branch 'blender2.8' into greasepencil-object

Cleanup: remove unused line

Add warning if mode is not supported

Warning user if try to use a non supported set origin option

Remove custom set origin operator

This change has been integrated in standard set origin operator

Include set origin in standard origin operator

Add menu to set origin operator

In order to keep the UI consistency I have added a menu.

This menu has only one option, but the UI panel looks more consistent

Move Group and ParticleSettings to new copying system.

Also fix several mistakes from previous commits.

Move World and MovieClip to new copying system.

Rename new `BKE_<foo>_copy_ex` to `BKE_<foo>_copy_data`.

Those are not actually copying the ID, only its internal subdata (and
other ID-specific handling). Generic processing common to all ID copying
is done by `BKE_id_copy_ex()`!

Move Material, Texture and Image datablocks to new copying code.

Note that this is also bringing back Image copying code into 'regular'
process, instead of doing its own dirty cooking.

added the alpha channel in vpaint a slider and change in ply exporter
