Fix background_job template

Update attribute and use empty file operator

Merge branch 'master' into blender2.8

Draw Manager: Edit Mode: Curve: uniforms were not being setted

Fix T53748: uniform `globalsBlock` was not being added was not being added to the shaders of the curves handles

Correct typos

Fix T53491: Absolute tablet motion detection fails

When using a tablet, detecting absolute motion only worked
when activating a tool with the tablet.

Pressing Enter to run a tool for e.g. would use relative motion.

Now store is_motion_absolute in the event,
set for new events based on the most recent motion events.

fix t53701 minimal changes to get it working right

Curve/Surface Display: UV support

Fix (unreported) potential crash.

RNA_pointer_as_string could return NULL instead of a valid string in some cases.

Eevee: Fix AO in planar reflections.

Eevee: Fix Planar probe refresh.

Task scheduler: Use single thread branch when range fits into single chunk

Task scheduler: Fix wrong tasks calculation when chunk size is too big

Eevee: Support for dupli lamps without shadows.

Eevee: Fix crash with volumetrics.

Task scheduler: Use const qualifiers in parallel range

Task scheduler: Avoid over-allocation of tasks for parallel ranges

This seems to only cause extra rthreading overhead on systems with 10s of
threads, without actually solving anything.

Task scheduler: Add minimum number of iterations per thread in parallel range

The idea is to support following: allow doing parallel for on a small range,
each iteration of which takes lots of compute power, but limit such range to
a subset of threads.

For example, on a machine with 44 threads we can occupy 4 threads to handle
range of 64 elements, 16 elements per thread, where each block of 16 elements
is very complex to compute.

The idea should be to use this setting instead of global use_threading flag,
which is only based on size of array. Proper use of the new flag will improve
threadability.

This commit only contains internal task scheduler changes, this setting is not
used yet by any areas.

Task scheduler: Simplify parallel range function

Basically, split it up and avoid extra abstraction level.
