Scopes were moved to properties area, so need to adjust
the optimization part of tagging.
Ideally, tagging will always happen (and happen for free)
and then drawing code will update scopes when they are
actually displayed. But this is outside of the scope of
this fix since requires some design changes.
The issue was caused by dependency graph resetting particles
when evaluating copy-on-write version of object. Solved by
only doing reset from dependency graph on user edits.
Other issue was caused by modifier itself trying to compare
topology and reset particles when number of vertices or faces
changed. This isn't reliable, since topology might change even
with same number of elements. But also, since copy-on-written
object initially always have those fields zero-ed the reset
was happening on every F12.
The latter issue is solved by moving reset from modifier stack
to places where we exit edit/paint modes which might be changing
topology.
There is still weird issue of particles generated at some
weird location after tapping tab twice, but this is not a new
issue in 2.8 branch and is to be looked separately.
Was missing synchronization of current frame to the original one,
which is one of the issues why point cache does not properly reset
on edits.
Also clear recalc flag on original particle system.
Ideally we need to get rid of recalc on a particle system, since
that is not really covered by tagging system of dependency graph.
Some summary of changes:
- Don't use DEG prefix for types and enumerator values:
the code is already inside DEG namespace.
- Put code where it locally belongs to: avoid having one
single header file with all sort of definitions in it.
- Take advantage of modern C++11 enabled by default.
Was happening when value of one shape key was driving property of
another shape key of same datablock.
Solved by making shape key blocks properties more granular.
Makes it more explicit whether RNA property is used as a source
dependency for something else, or whether some other dependency
is being hooked up to evaluate that property.
This is necessary when adding a new keyframe to a fcurve
that also has a driver.

This removes a bunch of animation/driver evaluations and recalc flags that
should be redundant in the new depsgraph, and were incorrectly affecting
the evaluated scene in a permanent way.
Still two cases that could be removed if the depsgraph is improved, in
BKE_object_handle_data_update and BKE_cachefile_update_frame.
For physics subframe interpolation there are also still calls to
BKE_object_where_is_calc that should ideally be removed as well, though
they are not known to cause keyframing bugs.

Some features are incompatible with multithreading and reliable evaluation
of dependencies. We are now removing them as part of a bigger cleanup to
fix bugs in keyframing and invalid animation evaluations.
* Dupliframes have been removed. This was a hack added before there were
more powerful features like the array modifier.
* Slow parent has been removed, never worked in 2.8. It was always
unreliable for use in production due to depending on whatever frame was
previously evaluated, which was not always the previous frame.
* Particle instanced objects used to have their transform evaluated at
the particle time. Now it always gets the current time transform.
* Boids can no longer do predictive avoidance of force field objects,
but still for other particles.

While this is harmless, it did cause T55399 in the past.
Sculpt adds it's own undo steps, so don't request the operator type
to do it too.
This is consistent with other sculpt operators.
Issue actually exists since ages, probably 2.7x update system forced all
armature proxies to be fully refreshed after an undo?
In any case, proxy_from should only be reset for 'local' proxies (i.e.
directly linked datablocks), not for linked proxies...
Only keep this function when drawing to avoid COW overhead that reduce performance.
After some changes I did some time ago, the use of original ID was not required and this only added depsgraph overhead and problems.
This change solves the problems with updates in render mode.
Related to T57484 and the changes requested by Sergey.
Kind of funny to see that this has been missing presumably since the
first version of library linking in Blender, and only gets noticed now.
Then again, that was not really a critical issue, iirc write code
ensures all libraries directly used get properly written, even if flags
are incorrect.
Add the ability for undo steps to request memfile undo step added after
them, useful for mode switching, where we need the data to exist for
undo to enter the mode.
This is only partially working, because some bAnimListElem items do not
have any ID pointer set (for wome mysterious reason...), notably the
'group' ones.
Will re-assign to @aligorith for that, this code is rather complicated
and hard to follow (with all those macros ;) ).
Support the alpha channel use of the object color in solid mode.
The Transparency effect is still using the Xray algorithm and not
true Alpha blending.
This adds the posibility of having certain materials transparent in solid
mode. The option is (for now) per material only and thus only shows in
material color mode.
This uses the same rendering technique as Xray mode.
Note that objects are not considered transparent for selection with this.
