Cleanup: DNA comment regarding ID for collections in outliner

Merge branch 'blender2.8' into greasepencil-object

Apply falloff to Scale

Apply falloff to rotation

Fix drag and drop in outliner for scene collections

This technically reverts 176698b2eb7f.

Drag and drop for scene collections requires id for its poll function. However
we were passing the collection as id pointer for outliner_add_element
(which is ok since the function doesn't require a real ID).

I couldn't reproduce the original issue tackled by the forementioned commit so
I'm going ahead and bringing drag and drop back for scene collections.

Note: We already pass the ID for view layer collections as well since we brought
collections into groups.

Apply falloff to transform

Outliner: Fix for restriction columns

This is a partial revert of 1f5106de610b115b87.

First and firemost, for groups I was checking the wrong flag
(soops->flag & SO_GROUPS) instead of (soops->outlinevis == SO_GROUPS).

Second, the columns were entirely broken for things like Orphan Data.

Third, I tried to have different columns for different `outlinevis`, but we have
bones with only visible and select, modifiers with visible and render, render
passes with enable and another value ... I would rather stay away from this mess
at the moment, and stick to the more obvious bug fix.

Finally, there is a bug (not addressed here) where the whole line is selected,
regardless of the restriction column area. It should be fixed separately.

WIP: Save falloff factor for transformations

This data must be used by transformation to determine the effect of the change.

Also enabled the falloff option for edit mode.

Eevee: Make Ogl render sampling more correct

Result is less noisy ogl renders.

What this patch does:
- the draw loops gets accumulated into the output buffer.
- disable TXAA persmat jittering in ogl render since ogl render already does that.
- make noise texture update correct accross all draw loops. Previously it was reset between each FSAA samples.

DRW: Add viewport argument to DRW_draw_render_loop_offscreen

This way we can have persistent data accross different calls.

Fix T53696: Compositor HSV limits changed

Fix manipulator crash when modal operator doesn't run

Math Lib: add divide_floor_i

Integer division that floors on negative output (like Python's).

BMesh: move bridge tools stepping logic into macro

Also use floor division since regular division was giving a bias
on negative error values.

BLI_utildefines_iter: Use for iteration helpers

Fix T53143: Knife Crash after Grid Fill

BM_ELEM_INTERNAL_TAG flag wasn't ensured to be cleared.

Fix T53637: Keymap from app-template ignored

Addon's were also ignored

Revert "BLI_utildefines: Support SWAP macro with two args"

This reverts commit d749320e3b10161430bc4cb7dd92edb63712bf8c.

It's possible the container struct is larger,
we could do sizeof checks that falls back to memmove
but rather avoid complicating things.

Use custom SWAP macro for swapping userdef data

Avoids complicating the common case
