Fix T62125: snapping not working if invisible object is between you and the target

If we were not in x-ray/wireframe mode, the snapping would treat all
objects like they were in solid mode. This were not desirable if you
had objects that were in wire or bounding box display mode.

Now objects that are in bounding box mode is ignored (unless the object
is in edit mode) and objects with wire display mode is treated as if
they were in x-ray mode.

Fix T60171: Hair Particles Not Displaying in Viewport

This patch fixes T60171 by adding a dummy read from the `dummy` vertex attribute to `hair_get_pos_tan_binor_time` in `common_hair_lib.glsl`. Confirmed to work on my machine (macOS 10.14.4 Beta, Radeon R?9 M295X).

According to my experiments regarding this issue, the problem is triggered when all of the following conditions are met: (a) the shader has no vertex reads; (b) the index buffer is ? 256KiB. I can't really give an explanation of this misbehavior because of the video driver's closed-source nature.

Fix T58890: Sculpt Mode not updating in LookDev or Rendered

This fix is a hack and will slow down update performance. But at least,
all shading features are supported. This is only in "normal" sculpt mode
(no dyntopo, no multires).

Fix stashed full-screens returning to wrong layout

Steps to reproduce were:
* Maximize area (Shift+Spacebar in 2.7, Ctrl+Spacebar in 2.8)
* Open temp file browser (Ctrl+O)
* Cancel file browser (Esc) - should return to previous full-screen
* Press "Return to Previous" button
The previously maximized area would turn into a file-browser.

Note that the issue will still happen when opening old files saved while
in maximized area full-screen.

GPencil: Material panel is hidden after adding new material

This bug was introduced by previous Pin fix commit. Maybe it's not the best solution, but this bug is critical and need a quick fix.

This commit fix the problem, but not totally sure this is working fine with pin.

@dfelinto Could you review and adapt if required.

GPU Extension: Add OS defines

This makes possible to have os specific workaround inside the shaders.

Fix T57655: Crash opening 2.79 file saved with maximized area

During screen to workspace/workspace-layout conversion, the first layout
of each workspace would be activated. For temporary full-screens, this
used to be the full-screen layout (IIRC), apparently it's now the
the layout to return to on "Back to Previous". So the 'previous' layout
would be activated, not the full-screen one.
When actually pressing "Back to Previous" now, the operator would first
free the active layout (which it assumes to be the temp full-screen -
wrongly in this case) and then try to activate the non-full-screen one,
causing use-after-free.

Fix T62104: VertexGroup.add() doesn't push depsgraph update for the mesh.

When adding and removing weights from the python api, no depsgraph
updates were triggered. This would cause the mesh geometry to be out of
sync in the viewport if there were any modifiers that used the vertex
groups in question.

Fix T61737: Gizmo refresh issue

When using a transform.select_orientation keyboard shortcut, the
orientation change would not update the viewport.
So if you had the move gizmo visible, it would not change transform
orientation.

Fix active workspace changes when deleting workspace

Tested for multi-window as well, which failed with the previous code even
before we introduced ordered workspaces.

Fix crash when deleting workspaces too fast

Delete workspaces via the menu was not refreshing the workspace tabs
drawing. This way if you deleted the non-active workspace with the "e" shortcut
from the workspace tab context menu and clicked on the workspace tabs again, it
would crash.

A few notes:
* Deleting a non-active workspace is changing which workspace is then active,
which is really strange.

* Even when deleting the active workspace which workspace then becomes active
seems random.

* Using notifiers (ND_WORKSPACE_DELETE) to delete the workspace seems rather
abusing notifiers in my humble opinion.

This is not an important bugfix anyways, people probably would rarely
run into this. I just ran into it while investigating another bug.

Partially revert "Collection duplication from Outliner: add a 'duplicate hierarchy' operation."

This partially reverts commit a77feabb51470b9cfb71be7f0ea7e774d6591799,

Followup to T62318: Fix on-the-fly that kind of .blend file cddata corruption.

Remove cddata layers which are not supposed to be written in .blend file,
when reading it.

This is a cheap and simple check, which also gives us forward compatibility
in case we decide some day to make a currently un-written layer type
to be written in .blend files.
