BKE Collections: add helper to find the scene of a master collection.

Fix T62457: Crash with rigid body and disabled objects

Need to always ensure objects form rigid body wortld are part
of dependency graph.

Fix missing metadata for multilayer exr sequences

Merge branch 'blender2.7'

API Doc: Gotcha: add section about 'exceptions to the rules' known crashing cases.

As exposed in T62406, we can have some rare cases of crashes due to
memory re-allocation happening outside of expected scenarii.

Ideally this should be re-designed, but at least keep track of those
known exceptions to general rules...

Fix T62481: Cycles crash rendering with UV pass after recent changes.

Cycles/OpenCL: Reduce How Often Kernel Recompilations Are Needed

This patch will reduce the number of times that we need to
recompile kernels. It does this by (en/dis)abling features
by default. So when the user needs them that the kernels are
already available.

Other features are enabled by default for background and foreground
rendering. When in background rendering the user wants the best
render performance. When in foreground rendering the user wants
the least amount of recompilations.

Enabling volumetrics or subdivision evaluation will still trigger
a recompilation during foreground rendering.

Fix T62485: wrong tooltip text

Fix T62470: instanced object does not preserve bounds display type.

Inheriting the display type from the instancer should only happen if it's
a simpler one.

UI: Adjustments to Texture Paint Projection Paint panel

Make B-Bone deformation code more robust with bad cached segment data.

Various dependency graph problems can cause obsolete data to reach the
armature modifier, so add checks to reduce the chance of crashing.

GPencil: Set wire mode when object is set to wire

When the object view is set to Wireframe, the display must be set as wireframe view with x-ray on.

Now the x-ray switch is handled by object.

Cleanup: use doxygen sections for BLI_utildefines

Cleanup: BLI_utildefines struct macros

Use the term "AFTER" instead of "OFS" since it wasn't obvious these
macros operate on everything after the struct member passed.

Avoid casting to non-const types when only reading.

UI: Avoid redundant text argument to UnifiedPaintPanel methods

Now when the text argument is omitted, use the default name
matching how regular properties work.

Avoids passing in the same name which RNA has,
matches UILayout.prop behavior.

Also use keyword only for optional arguments.

RNA: support None text argument to UI functions

Without this there isn't a convenient way to write wrapper UI functions
that forward a text argument that optionally uses the default text.

Cleanup: use UnifiedPaintPanel for context menu

Fix use of uninitialized stack memory

The matrix multiply uses x,y values so both must be initialized.

DRW: use object color from instancer

Otherwise it's impossible to set the color of instanced library objects.

Follows convention of instancer controlling draw options.
