Sequencer: Fix missing FX compositor when starting rendering from frame with DoF disabled

Merge branch 'master' into blender2.8

Sequencer: Add option to render OpenGL preview with DoF

The title says it all actually, controlled with DoF check box next to textured
solid check box.

Thanks Campbell for review!

Refactor view3d offscreen drawing to avoid having multiple boolean arguments

This is fully unreadable to have lots of boolean arguments scattered across the
whole argument list. What does `false, true, true` mean in terms of behavior?

Replace those with bitfield which has advantage of having more human readable
meaning.

small fix for inflow levelset

clear after initial frame to avoid sampling snd parts twice

updated manta pp files

Merge branch 'blender2.8' into greasepencil-object

Cycles: Split shader_eval out of the kernel_lamp_emission kernel

With this kernels for BWM and classroom scenes are building in half the
time as master. Render times are 1% faster as well.

Tracking: Cleanup. make code friendly for multi-column editing

Cycles: Split kernel_path_lamp_emission

Cycles: Split indirect_lamp_emission

Cycles: Only use first lamp in indirect_lamp_emission

Produces different results when lamps overlap from POV of a ray, but allows
for this function to be split. The differences probably wont be noticeable
in most scenes. Old behavior could be reattained by placing lamps
into the BVH.

WM: don't change selection on workspace append

Tool System: show manipulators at startup

Support duplicating, switching workspaces too.

Fix crash duplicating workspace

Cycles: Fix mistake with ShaderEvalTask that could lead to crash

Manipulator: ignore depth-buffer for scale cage

Cleanup: incorrect comment

WM: handle widgets before tool keymaps

Allows adjusting on-screen widgets even when a tool is selected.

Cycles: Merge shadow_blocked_ao and _dl kernels to improve build times

Gives another 4 seconds improvement.
