Revert "Revert "Revert "Temporarily disable material preview (T51796 workaround)"""

This reverts commit 6df053e527b2808767f3a3417e1e7d683b979149.

Depsgraph: Use explicit bmain pointer passed to layer utilities

it is not necessarily that depsgraph is built from G.bmain.

This will solve issue reported in T51782.

Depsgraph: Fix wrong layer used

Should be context, not render active one here.

Revert "Revert "Temporarily disable material preview (T51796 workaround)""

The "fix" happened due to a mistake in copy-on-write commit, that mistake solved
preview render but broke something else.

This reverts commit 45720922f7b927865b9b63f31c9d2a0b3d4b753e.

Fix (unreported) Scene copying doing very stupid things with World and LineStyle usercounts.

Really, really, really need to get rid of this usercount handling
everywhere, hopefully incomming ID copying rewrite will help sanitize
that mess. But fix was needed for 2.79 release!

Fix T51931: VBO not updating when UVs are added to shader node tree

UVs need specific data in the VBO, which is not computed unless the
shaders assigned to the mesh actually use UVs. When adding UVs to the
shader, the VBOs were not being recomputed to include the required data.

This adds a DEG relation between the shader and the mesh, and recomputes
the required data if the shader changed.

Thanks Sergey, for all the DEG stuff...

Partial fix of T51989: Don't set image user offset for movie files

While this is handy for image sequences, it's totally meaningless for movie files.

Fix T52011: Border render is incorrect with multiple scenes

The code was somewhat weird: it was first copying border/crop settings from
the "source" scene, then was checking border settings of the current scene
and only then was copying border from "source" scene.

Now we first copy border/crop flags, then copy border from source and then
check whether border is a full-frame.

Fix image empties not drawing

A pointer to the uniform data for the empty drawing was being freed
before the actual draw call, which invalidates the uniform.

This makes the data only be freed after drawing.

Error in last commit

Fix T51998: Anim player uses 100% CPU

The loop running with no events didn't sleep.
Now wait for events when paused.

Fix T51052: CacheFile Open crashes from Python

Note that bpy.data access makes more sense here,
but better not crash when called from Python.

Fix T51665: No orientation for nurbs, polygons

Curve: add assert for invalid next/prev use

Fix T52007: Cancel bezier curve transform fails

Auto & aligned handles wouldn't restore to their correct locations.

Note that a more direct fix for the bug is possible
(storing the handle locations to restore on cancel).

But that still gives some odd behavior, see code-comments for details.

Fix T51898: missing sequence strip color space validation on load.
