first working fluid guiding setup in smoke script

Manipulator: correct cage-2d scale update

Cleanup: prefer tuples over lists

adapted spiral velocity getter from mantaflow

2.79 release: point submodules to correct branches and versions.

2.79 release: new splash, yeah!

Render: make Cycles and Evee support each other's output material nodes.

This changes the Cycles exporting and Cycles/Eevee UI code to support both
output material nodes, giving priority to the renderer native one. Still
missing is Eevee code to prefer the Eevee output node.

UI: Hide options in weight paint mode

Tweak multi-units tests to match new precision handling in conversion from raw value to prety-printed one.

Note that new code allows to enable again the '1 million miles' tests.

Fix multi-units drawing re precision handling.

This is still far from prefect, but yet much better than what we had so
far (more consistent with inheritent precision available in floats).

Note that this fixes some (currently commented out) units unittests, and
requires adjusting some others, will be done in next commit.

BLI_math: add simple helper to get amount of 'integer' digits in a float number.

Merge branch 'blender2.8' into topbar

Show theme options for tags in UserPrefs

Also fix buffer out-of-range access and default color of tab outline.
