Cleanup: unused arg

Cleanup: macro hygiene, line length

Merge branch 'blender2.8' into userpref_redesign

Use term "Preferences" instead of "User Preferences" in the UI

More small tweaks/fixes to new Preferences

* Fixed gap in Viewports panel
* Made all buttons to install things (Addons, Lights, Keymaps, Themes etc) use the same icon and use elipses (...) to communicate the fact that they open a dialog.
* Fixed own code error in Input > View panel
* Re-ordered panels in Input section - now related Mouse and Devices panels are next to each other
* Renamed User Preferences in the Editor list to just Preferences - consistent with Edit > Preferences
* Removed icon for auto-key toggle - doesn't fit here

Mesh Batch Cache: Fix missing flag for looptris indexbuf generation

Fix T59637: Crash report - Overlays -> Face Orientation causes crash

Workbench: Fix wrong TEXTURE_DRAWING_ENABLED check and rework drawing logic

This makes the code easier to follow. Batches are now assumed to be not
NULL as the request system garatees it.

UI: use smaller widget for expanding hidden region

The '+' widget to show a hidden region came too close to overlapping
the viewport navigation gizmo and text editor text.

Reduce size and use an arrow icon.

Library: correct BKE_id_to_unique_string_key fix

GP: Use only selected points to calc transform center

GP: Enable center for Local Origins only

This produces very interesting effects when move using proportional editing.

GP: Undo center calculation

This is breaking the transformation with falloff enabled.

Merge branch 'blender2.8' into greasepencil-object

GP: Change default parameters for convert curves.

Now the link strokes is disabled by default.

Also some minor changes to adapt to new GP object.

Fix T59648: Linking material to greasepencil object causes crash

GP: Changes in API to make internal update

Now, the internal data is recalculated when add or remove a point.

The change in the API affect to stroke.points.add() that now requires a datablock parameter. This parameter is required to identify the datablock affected.

For example: stroke.points.add(gpencil, 1) instead of stroke.points.add(1)

This is the second try to fix T59600

Merge branch 'master' into blender2.8

Cycles: Fixes for recent curve robustness

The key indices were wrong: need to offset curve key index
by first curve key index. Also corrected calculation of the
interpolation step.

Annoyingly, can not reproduce this on a simple file, need
production rig. For the possible future look the following
file from Spring was used: 03_005_A.lighting.debug.blend

GP: Fix merge conflict

Fix tool system integration of hair edit brushes.
