Make Dots mode thickness equal to Line mode

The dots was using half of thickness and when change the mode to line, the line was thicker.

Now, both thickness are equal.

Merge branch 'blender2.8' into greasepencil-object

Add missing NULL check

Caused loading user-prefs to crash.

Merge branch 'master' into blender2.8

Cleanup: edit-mode undo API

Move function descriptions into the struct,
minor improvements to variable naming,
use convention of 'g_' prefix for static vars.

DRW: Fix memory leak.

This prevents the creation of a new job if no job is running.

Eevee: Fix volume rendering glitches.

The bug was due to the Halton function returning uninitialized value for 0 iteration.

Eevee: Fix garbage on the first frames when enabling volumetrics.

Was cause by newly added shader deferred compilation.

Draw Manager: Simplify the algorithm that extract the BoundingSphere of a Frustum

The idea is to separate the most common case from symmetrical frustum. And to make a simple but efficient calculation.

The new radius is usually 98% the size of the radius size of the asymmetric solution.

Thanks to @fclem for reviewing the patch on IRC

WIP: Integrate Cycles render

This is the first try to integrate the Cycles render with Grease Pencil.

Eevee uses its own call and don't need all this stuff because reuse all Eevee initialization code.

Eevee: Fix crash with volumetrics + default mat + alpha blend

Eevee: Fix Cascaded shadowmap setup.

It was getting the wrong matrice because of the point light override.

DRW: Fix DRW_viewport_matrix_override_set_all function.

Eevee: Fix probes not working after a world update.

Eevee: Update to support shader deferred compilation.

World probe is tagged to refresh when it it's shader is updated.
Probes are recomputed only after all meshes shaders have been compiled.

GPU: Fix typo.

DRW: Fix broken grid in ortho view.

Eevee: fix wrong sizeof.

Like really? wtf dude? *self face slapping*

DRW: Shader Deferred compilation: Use a wmJob for threading.

Also get rid of the static var and initialization.
This enables the user to see the progress on the info header.
Closing blender or reading a file also kill the job which is good.

Unfortunatly, this job cannot be interrupt by users directly. We could make it interruptible but we need a way to resume the compilation.
