Add TODO for xray functionality

Remove deprecated opengl stuff from opensubdiv

This removes glGetBooleanv queries for GL_LIGHTING. This has been #ifdef'd
out with legacy opengl disabled. Thus a false positive still shows up in
the gl queries. Also, note that this removes support for wireframes in
opensubdiv, when desabling legacy opengl, which should be fixed later.

Part of T49043

Remove some elbeem debug functions

Some elbeem debug functions had old gl drawing calls. I removed the
functions instead of converting, because Blender doesn't even build
with them enabled anymore, because some elbeem debug libs got removed
at some point.

Part of T49043

Alembic export: unified code of exploreTransform and exploreObject.

Alembic export: added support for writing dupli-groups

This supports our common character animation workflow, where a character,
its rig, and the custom bone shapes are all part of a group. This group
is then linked into the scene, the rig is proxified and animated. Such
a group can now be exported. Use "Renderable objects only" to prevent
writing the custom bone shapes to the Alembic file.

SLIM: disallowing pins to move to places that the SLIM algorithm can't handle. Also, this simplifiey the way we transfer uv coords back to native part.

Unittests for depsgraph layer collection render settings evaluation

Some of the tests are failing at the moment.
Those problems were introduced in eba09b1520

SLIM: In live Unwrap mode unpinned vertices can now be moved. Also, a single pin also invokes SLIM. That also avoids crashing minimize_stretch when invoked on chart with one pin.

Merge branch 'master' into cloth-improvements

Fix Surface Deform crash with missing or freed DM

Update despsgraph when set/unset variables

Layer collection settings API

This way we can set a property via RNA, and also force an update of scene layer (which I am using for unittesting)

Cleanup: Use macro to free shaders

Cycles: Make vectorized types constructor from register explicit

This is not a cheap operation which we dont' want to happen silently.

Cycles: Remove unused function

It was quite wrong actually by doing some __m128 to flaot4 round trips.

Alembic import: fixed off-by-one error in start/end frame

static_cast<int> truncates, so a computed end frame of 99.999999999998
would result in 99, instead of the correct 100.

Draw Manager: initial lattice support

Still misses support for edit-mode selection & weight drawing.

Cleanup: minor changes to logic for outline drawing

Use brace placement following code-style too.

Task scheduler: Fix typo in TLS for pools created from non-main thread

Did a mistake which started to use same TLS for all threads for such pools.

Also added some extra asserts to help catching the bugs.
