GP: Don't use offset for Stroke projection

The offset is only used in Surface mode.

Fix T60015: snap to grid - snaps only to largest increment

Caused by rBc7a96651dfa4 when trying to remove all uses of the deprecated `rv3d->gridview`.

Outliner: expand view layer collections by default, revealing objects.

Templates: tweaks to startup templates.

* 2D Animation: lots of changes from the grease pencil team. Properties
editor layouts, brush and material settings, and more.
* 3D Viewport: wireframes set to 1.0.
* World: use nodes by default.
* Node Editor: use narrow toolbar.

Viewport: update default set of HDR images.

Add city, courtyard and interior HDRs. Replace grass field and night
HDR with different images.

Command used for compression:
oiiotool %s --resize 1024x512 --ch R,G,B -d float --compression dwab:300 -o output/%s

Cleanup: remove unused camera studio lights.

Cleanup: specify default studiolight name, instead using first alphabetically.

Fix T59991: duplicate entries for node select operators in keymap.

Ref D4055.

UI: icon set updates by Andrzej Ambroz.

Fix: Cramped layout in object parent properties

Cleanup: remove non-existing function declarations

GP: Mew Merge Strokes operator

This operator allows to create a new stroke joining several selected points of different strokes.

The new stroke will use the current material.

To use, first select the points to be merged. Optionally can remove the old points and strokes.

The operator is available in Edit mode in the Specials menu and Stroke menu.

Cleanup: warnings (clang)

Fix: Scrolling Preferences could cause blank UI

Steps to reproduce were:
* Open Preferences
* Choose "Input" category
* Scroll to the bottom
* Choose "Interface" category

The newly activated category should now use the scrolling set previously
in the other category, causing the contents to be out of view. You
would have to scroll to bring it back.

Now scrolling is stored per category.

Fix T59675: Motion path frame numbers at wrong positions

Cleanup: avoid counting list multiple times

Also simplify selected sequencer length function.

Cleanup: use bool, style

Cycles: restore old sample and material override settings for view layers.

Since there will be no view layer overrides in 2.80, this is needed still.

Fix T57078: Alembic curve import: better check for topology similarity

The old code assumed that if the number of curves was the same, the
entire set of curves would have the same topology (in other words, it
assumed 'same number of curves => same number of vertices for each
curve').

I've added a more thorough check that also considers the number of
vertices in each curve. This still keeps certain assumptions in place
(for example that if the topology is the same, the weights won't change,
which is not necessarily true). However, when the assumption doesn't
hold, at least now Blender doesn't crash any more.

Fix T59164: Run Alembic in background when INVOKE'd

This is similar to what physics baking is doing: invoking the operator
runs a background job, whereas executing blocks. This makes Python
scripts calling the Alembic import/export operators more predictable.

For backwardward compatibility with existing Python code the
`as_background_job` parameter still exists, which overrides the
behaviour chosen by INVOKE/EXECUTE.
