adaptive_cloth: AdaptiveMesh: split_edges: run flip_edges()

On the faces that were added by the split edge operation, run the
flip_edges() function.

adaptive_cloth: AdaptiveMesh: flip_edges()

Flips edges of the `active_faces` if needed.

* Get the maximally independent set of flippable `AdaptiveEdge`s.
* Flip each edge in this set and update `active_faces` with the faces
affected by this operation.
* Repeat until the set has 0 flippable `AdaptiveEdge`s

adaptive_cloth: AdaptiveMesh: get_flippable_edge_indices_set()

Similar to get_splittable_edge_indices_set() it checks for
flippability of the `AdaptiveEdge` instead of the "size" of the
`AdaptiveEdge`.

adaptive_cloth: AdaptiveMesh: is_edge_flippable_anisotropic_aware()

Function to check if the given `Edge` is flippable or not by adding an
anisotropic aware check.

Based on reference [1].

Cleanup: Comments

adaptive_cloth: AdaptiveMesh: VertFlags: VERT_SELECTED_FOR_SPLIT

rename `VERT_SELECTED` to `VERT_SELECTED_FOR_SPLIT` for more explicit
meaning

adaptive_cloth: AdaptiveMesh: Sizing: overload add and mul ops

Overload the operators to allow operations on `Sizing` itself. This
will help in case `Sizing` will need to change in the future maybe for
adaptive tearing support.

adaptive_cloth: Mesh: does_element_exist()

Set of functions to test if the element still exists in the `Mesh`
when given it's index.

adaptive_cloth: Mesh: checked and unchecked get_other_vert_index()

`get_checked_other_vert_index()` a new checked version of
`get_other_vert_index()`

Update `get_other_vert_index()` to have better checks

adaptive_cloth: Mesh: Edge: get_checked_verts()

adaptive_cloth: Mesh: make get_edge_indices_of_face() as protected

GPencil: Fix empty preview image

As the render preview uses a new scene, the active frame is set to 1, but grease pencil needs to have the current frame in the right place to display the strokes. Now the current frame number in the original frame is passes to scene creation function to set the same frame in the preview temporal scene.

GPencil: Fix error in layers order

Before was inverted because a bug

GPencil: Fix infinite loop when importing to new object

GPencil: Avoid segment fault when material is NULL

Merge branch 'master' into xr-controller-support

Fix build errors/warnings on some platforms

MCE: Only draw annotation placement panel with Clip

The annotation placement panel only makes sense when the Data Source is
CLIP, when TRACK is use the anntation placement options don't apply.
