Outliner: Add extend selection to walk select

Walk select now extends the selection when shift is pressed.
This implementation works well, though if there are existing
selections in the tree the behavior may not work as expected.
This could be improved on in the future if that is a problem.

Outliner: Fix tree building not setting parents properly

When the scenes view tree was built, the parent for view layers
and objects were not set properly (either NULL or incorrect
parent), causing walk select to fail. Now the proper parents are
set.

Not sure if there was a reason why the wrong parent was set for
view layers before.

Outliner: Fix walk selection wrapping and other issues

This prevents walk selection from wrapping around from the last
to the first tree element. Additionally, if the active tree
element is within a closed subtree, walk select will move the
active element to the first visible parent.

The operator code is also simplified and slightly optimized.

Custom bevel profiles: Merged calculate_profile and calculate_profile_custom.

Now that I'm using the custom profile for all bevel cases, I don't need to have
separate code that uses the custom bevel profiles, so I only need one function.

This also changes the "reversed" parameter to flip the order of the calculated
profile so it doesn't have to be done later with get_profile_point indices.

Fix compile/CMake errors and warnings on Linux

Comments: Updated questions in comments marked with HANS-QUESTION. Deleted solved questions.

Fix 2D noise_grad function

Finish VR view drawing callback set up

* Allow passing custom data to session draw function, passed to the
callback
* Actually call the callback
* Create and bind a WM level callback. Will later be used to draw the
viewport.

Also, check if session is actually visible before drawing.

GPencil: Remove redundant parameter

Don't use Microsoft::WRL::ComPtr<...> for COM types

Makes things difficult if you're not familar with COM.

GPencil: Initial changes to redesign the layers blend modes.

These changes were proposed by @fclem in order to make more efficient the engine.

Still WIP: NO layers blend modes working and no clamp.

DRW: Add RGBA16 support for framebuffers

This avoid assert.

use one block allocator per thread instead of per block

USD: support for simple preview materials

Very simple versions of the materials are now exported, using only the
viewport diffuse RGB, metallic, and roughness.

When there are multiple materials, the mesh faces are stored as geometry
subset and each material is assigned to the appropriate subset. If there
is only one material this is skipped.

The first material if any) is always applied to the mesh itself
(regardless of the existence of geometry subsets), because the Hydra
viewport doesn't support materials on subsets. See
https://github.com/PixarAnimationStudios/USD/issues/542 for more info.

Note that the geometry subsets are not yet time-sampled, so it will
break when an animated mesh changes topology.
