Fix UI warning

Fix problem with merge down

The problem was if the layer below had animation in frames not present in top layer. As the active frame of top layer was the previous keyframe, after merging, the draw of bottom layer replaced the draw of top layer and the result was that some drawings were missing.

The solution was to duplicate the active frame in top layer before merge the bottom layer.

Depsgraph: Cleanup, line length

Depsgraph: Use named typedef for tag

Depsgraph: Cleanup, typo in comment

Merge branch 'master' into blender2.8

Depsgraph: Add facilities to store what ID recalc flag component corresponds to

The idea is to de-duplicate logic in DEG_id_tag_update() and flushing where we
need to translate depsgraph tag or component type to ID level recalc flag.

Currently unused, but is required for Blender 2.8.

Add dedicated named constant for no ID recalc flag

Merge branch 'master' into blender2.8

Depsgraph: Synchronize flushing with 2.8 branch

Not only this helps merges form master to the branch, but also:

- Allows us to production-check changes as soon as possible.
- Avoids some unnecessary editors update about ID changes.
- Adds small optimization on queue size by always keeping one of the pointers
outside of the queue.

Merge branch 'master' into blender2.8

Depsgraph: Add query API to traverse all dependent IDs of the given ID

Depsgraph: Replace iteration over ghash with iteration over flat array

Depsgraph: Introduce flat list of ID nodes

The idea is to allow iterating over ID nodes in exact order of their
construction, and in order which will not change dependent on memory
pointers or anything.

Fix bad merge happened at some point

Fix T53398: Surface deform modifier says that convex polygons are concave for big faces

Dot-product for angle check need either to be divided by vectors magnitude or be
calculated for normalized vectors.

Fix: Don't assume that rect starts from 0,0

Fix: Missed these in last commit

Cleanup - Save off multiedit state instead of querying it all the time

Cleanup - Split out the GP stroke sculpting loop-over-strokes logic into a separate function
