Restore part of comment for xray_mode, left out during earlier fix

Remove last_palette_name field

This isn't used for anything anymore. Removing it (and the padding) doesn't
seem to cause any new glitches, so this should be ok.

Merge branch 'master' into blender2.8

WM: immediate line-gesture activation on tweak

Matches border-gesture behavior,
needed for binding bisect to tweak event.

GPUFramebuffer: Fix recursive downsample exiting early.

I should really proof read my commits a bit more.

Knife Tool: add wait_for_event option

GPU Extension: Fix AMD Vega + open source driver detection.

Docs: Add comments on workspace removal functions

Fix warnings for notifier listeners

Fix for objects trailing in viewport when using BI in scene+Eevee in workspace

Thanks for Cl�ment Foucault for finding where to tackle.

Fixup for recent workspace changes: Python files

I wrongly changed some of these files via sed, and apparently overdid
it in some false positives.

Silence warning

Workspace: Call BKE_viewrender_free from the right place

We should call it when we free the workspace, not when removing it.
Patch by Julian Eisel.

Workspace: Move engines to workspace and Properties Editor cleanup

Engine is not stored in WorkSpaces. That defines the "context" engine, which
is used for the entire UI.

The engine used for the poll of nodes (add node menu, new nodes when "Use Nodes")
is obtained from context.

Introduce a ViewRender struct for viewport settings that are defined for
workspaces and scene. This struct will be populated with the hand-picked
settings that can be defined per workspace as per the 2.8 design.

* use_scene_settings
* properties editor: workshop + organize context path

Use Scene Settings
==================
For viewport drawing, Workspaces have an option to use the Scene render
settings (F12) instead of the viewport settings.

This way users can quickly preview the final render settings, engine and
View Layer. This will affect all the editors in that workspace, and it will be
clearly indicated in the top-bar.

Properties Editor: Add Workspace and organize context path
==========================================================

We now have the properties of:

Scene, Scene > Layer, Scene > World, Workspace

[Scene | Workspace] > Render Layer > Object
[Scene | Workspace] > Render Layer > Object > Data
(...)

Fix compatibility flag for nodetree

NODE_NEWER_SHADING was introduced in e868b459bb8e however it should have been
added as a bitflag.

BKE_scene_uses_blender_eevee() was used in gpu_shader_output() as a workaround
for compatibility being poorly used.

Anyways this fixes this situation. This is necessary for an upcoming patch, even
though this is considered temporary - since the other NODE_*_SHADING values are
legacy from Blender Internal drawing.

Code Cleanup - Remove all uses of gpd->last_palette_name

The reason for this has been superseeded by the Palette Slots system

Replace freeing checks with MEM_SAFE_FREE

Merge branch 'master' into blender2.8

WM: refactor gestures for use as tools

Border and circle select wait for input by default.
This commit uses bool properties on the operators instead of
magic number (called "gesture_mode").

Keymaps that define 'deselect' for border/circle select
begin immediately, exiting when on button release.
