Fix T57656: Keyframes cannot be selected in Grease Pencil Dopesheet.

Partial revert of rBf250f9256e065: GP and masks use integer
frames, so float code isn't working or even needed.

Merge branch 'master' into blender2.8

UI: change Cycles render panels organization.

Move geometry panels to top level, move device/OSL back to top, and
various other changes.

Fix T56055: color discrepancy between viewport and render for Filmic transforms.

Shrinkwrap: new mode that projects along the target normal.

The Nearest Surface Point shrink method, while fast, is neither
smooth nor continuous: as the source point moves, the projected
point can both stop and jump. This causes distortions in the
deformation of the shrinkwrap modifier, and the motion of an
animated object with a shrinkwrap constraint.

This patch implements a new mode, which, instead of using the simple
nearest point search, iteratively solves an equation for each triangle
to find a point which has its interpolated normal point to or from the
original vertex. Non-manifold boundary edges are treated as infinitely
thin cylinders that cast normals in all perpendicular directions.

Since this is useful for the constraint, and having multiple
objects with constraints targeting the same guide mesh is a quite
reasonable use case, rather than calculating the mesh boundary edge
data over and over again, it is precomputed and cached in the mesh.

BKE_mesh: add a utility to get edge indices from looptri.

Not all three sides of a tesselated mesh triangle are guaranteed
to be original mesh edges, so a somewhat complicated check is
required to detect which ones are real. It seems that until now
there was no utility function for that, only some example code.

BLI_kdopbvh: add an option to use a priority queue in find_nearest.

Simple find_nearest relies on a heuristic for efficient culling of
the BVH tree, which involves a fast callback that always updates the
result, and the caller reusing the result of the previous find_nearest
to prime the process for the next vertex.

If the callback is slow and/or applies significant restrictions on
what kind of nodes can qualify for the result, the heuristic can't
work. Thus for such tasks it is necessary to order and prune nodes
before the callback at BVH tree level using a priority queue.

Since, according to code history, for simple find_nearest the
heuristic approach is faster, this mode has to be an option.

Defaults: disable AV Sync by default again, it breaks physics caching.

This reverts back to the 2.79 situation. The better solution would be to make
physics caching somehow simulate the skipped frames. But for now the more
important thing is to have working physics.

UI: some reordering of Cycles panels.

Fix/cleanup RNA viewlayer API.

RNA's ViewLayer would present 'first level' of layer collection as a
list (collection property), when it is actually now only a single item,
same as the scene's master collection.

Note: did not try to update view_layer python tests, those are already
fully broken for quiet some time I guess (they still assume
view_layer.collections to be mutable e.g.)...

Proper fix for new 'SimpleHeap' gtests...

This reverts reverting commit rB55324b8a2e6799300, and do proper 'cleanup' (sigh)
in gtest as well.

Sorry for the noise, did not understood what had happened here
immediately. :/

Revert rBfee6ab18e7e9 in BLI_heap_test.cc

Most certainly commite by mistake, FastHeap is not in BLI yet!

Cleanup: No need to save/restor frame buffer twice

GPU: frame buffer stack

UI: Tooltip for context properties too verbose.

"Type of active data to display and edit" is a bit too descriptive and takes
away from reading which context we're actually viewing. Also minor tweaks to
context description.

GP: Fix unreported error moving material slots

Multires: Refactor propagation to the higher levels

Now it is forumlated in terms of deltas, and consists of the
following steps:

- Original displacement at the reshape level are being backed up.
- New displacement is being written by the reshape routines.
- Delta of the displacement is calculated.
- Deltas are propagated to the higher levels, which also includes
their interpolation/
- Original displacement is restored.
- New interpolated displacements are added to the original ones.

This is a base ground for the upcoming change related on using
Catmull-Clark smoothing for the deltas instead of linear
interpolation. Currently is no changes for artists, just preparing
for upcoming work.

Eevee: Make nodegroup fix recursive.

Eevee: Fix broken shader if only using an Ambient Occlusion node

This quick fix does generate some invalid uniform. Will fix that later on.

Eevee: Fix missing UBO bound if using a muted Shader to RGB node with SSS

This is a nasty bug. Because the node does not get properlly tagged as SSS
(sss_id is 0) but is still evaluated (so tagging the GPUMaterial as having
SSS). The sssProfile UBO is still declared and we need to bind something
to it.
