Fix T49893: Crash in Video Sequence Editor with 'drop' effect.

Code was not accounting for possibilities that width or height of given
buffers may be smaller than XOFF/YOFF...

Note that I seriously doubt that drop code actually works (as in, gives
expected results) when applied to tiles like it seems to be done
currently, but this is much more complex (and involved) topic.

Remove unused include statement

Use proper defaults for Hue/Saturation node

Cycles :Cleanup, indentation

Depsgraph: Only re-schedule objects which are on visible layers

Otherwise it's possible to cause infinite update loop in Cycles viewport.

Gets a bit messy logic, need to revisit this..

Fix T50122: SEGFAULT: OCIO configuration typo leads to segfault

Fix T50003, Bevel makes non-manifold mesh.

Problem was setting prev/next faces for edges around
a vertex on valence-2 vertices.

Fix T50020: adding a background image does not set image user data.

UI: add a message to indicate when using a modifier that wasn't
compiled.

This adds a short message to the smoke, remesh and boolean modifiers' UI
when trying to use them when their compilation was turned off. This was
already implemented for the fluid and ocean simulation modifiers.

This also makes the 'quick fluid' and 'quick smoke' operator abort and
report when trying to use them when unavailable.

Depsgraph: Use HIGH priority for scheduled tasks

This kind of keeps threads "warmer" and should in theory give better
cache coherency bringing some %% of speedup. It was already tested
few months ago and it gave few % speedup in barber shop, but was
reverted due to some bone popping. The popping is now fixed so it
should be fine to use new scheduling policy.

Depsgraph: avoid more transitive relations for rigid body simulation

Depsgraph: Rigid body simulation doesn't need explicit time relation

It'll be dependent on time via Time Source -> Rebuild RB World chain.

Depsgraph: Avoid transitive relation from local transform to final

There is always an uber eval node on the way. so we can avoid creating
some relations here in order to speed up both construction time and
evaluation.

Fix depsgraph: hair collision is actually enabled, so add the relations.

Fix compilation error on recent Debian desktop

Something funny happened here, there were missing symbols from png
library to math functions.

3D cursor & mini axis for modern viewport

Shuffle existing code, hook it up to the new (& old) viewport.

Also the 3D mouse rotation guide for NEW viewport only. Minor feature not worth enabling for legacy 3D view.

OpenGL: delete bl_debug_draw

Eliminating this chunk of legacy GL as part of T49043.

We can introduce some sort of "debug plate" to fill this need in the future.

cleanup: C99 for view3d_draw

Mostly for clarity & to declare things close to where they are used.

I'm getting ready to do substantial work in these files.

Fix T50141: Nabla zero division on texture force field

This sets forces to zero, when Nabla is zero and a grayscale texture is
used or texture mode is Gradient or Curl.

Nabla equal to zero was causing a zero division, and forces ended up
being set to `nan`.
