Remove experimental brush

Set BOTH mode as default for fill brush

Fix old .dat file for object origin icon

Merge remote-tracking branch 'origin/blender2.8' into greasepencil-object

Leave it out uneeded changes from the .svg file

Merge remote-tracking branch 'origin/blender2.8' into greasepencil-object

Merge branch 'blender2.8' into greasepencil-object

Add option to reproject fill on Surface

Before, only origin was supported, now it can be reproject on object surface

Blender 2.79a: Use latest dev-tools

This way release checker used by Linux release environment is corrected.

Blender 2.79a: Show both version char and rc text on splash

Blender 2.79a: Use proper version char

Blender 2.79a: Point submodules to updated hash

Task scheduler: Start with suspended pool to avoid threading overhead on push

The idea is to avoid any threading overhead when we start pushing tasks in a
loop. Similarly to how we do it from the new dependency graph. Gives couple of
percent of speedup here, but also improves scalability.

Task scheduler: Clarify why do we need an atomic add of 0

Cycles: Fix crash opening user preferences after adding extra GPU

We can not store pointers to elements of collection property in the
case we modify that collection. This is like storing pointers to
elements of array before calling realloc().

Cycles tests: Add extra image tests

Fix T53012: Shadow catcher creates artifacts on contact area

The issue was caused by light sample being evaluated to nan at some point.
This is root of the cause which is to be fixed, but is very hard to trace down
especially via ssh (the issue only happens on AVX2 release build). Will give it
a closer look when back to my AVX2 machine.

For until then this is a good check to have anyway, it corresponds to what's
happening in regular radiance sum.

Fix retro-futuristical atempt to include some keymaps for non-backported feature from master.

Was making unittests unhappy.

Revert "Node selection: Stop operator when mouse selection selected a node"

This reverts commit bf58ec9265eef8c6cd3dc350557829151995ef28.

Cycles: Fix difference in image Clip extension method between CPU and GPU

Our own implementation was behaving different comparing to OSL and GPU,
namely on the border pixels OSL and CUDA was doing interpolation with
black, but we were clamping coordinate.

This partially fixes issue reported in T53452.

Similar change should also be done for 3D interpolation perhaps, but this
is to be investigated separately.
