Merge branch 'master' into blender2.8

Fix various Freestyle rendering bugs.

Gizmo: tweak 3D view navigation axis sizes

This now matches original design more closely, see: T54723.

Fix missing NULL check initializing paint tools

Tool System: support passing in args to ToolDef functions

Needed since class aren't yet defined
so we can't access their namespace.

This avoids intermediate draw functions.

Cleanup: style, use ARRAY_SET_ITEMS macro

GP: New API to move layers in layer list

This can be required in som production scripts

Fix T57388: Blender Internal + Freestyle viewport render wrongly using FSAA.

Fix assert rendering hair tests on some systems.

Fix assert rendering with denoising, after recent changes.

GP: Move init code to new version section

Fix T57611: Crash on entering Grease Pencil Sculpt Mode

The problem was when some layers was locked in multiedit. The cache size was not checked and gets an segment fault.

Simple hair curve generation function for the test operator.

GP: Time Offset verify range if loop is disabled

Remove the "bind" flag and function for hair.

This is a remnant of the previous system where actual fibers were always
interpolated from one or more actual curves. Now each follicle simply gets
its own curve.

GP: Reorganize Canvas Grid

Now the grid is always controlled by the topbar selector and not in the canvas panel. To have two places to define orientation was confuse.

The orientation by default (no lock) is always to view plane.

Merge remote-tracking branch 'origin/blender2.8' into hair_object

BLI_heap: add an API function to directly read the top node value.

It is very commonly needed in loop conditions to check if
the items in the heap are good enough to continue.

Merge branch 'master' into blender2.8

Fix ghash masking out upper bits on 64bit systems

The code this was taken from assumes a 'size_t' result,
which isn't the case here.

In practice the bucket distribution wasn't bad,
even so this was a nop so best fix.
