Added subsurface radius parameter to control the per color channel
effection radius of the subsurface scattering.

Rearranged the inputs of the shader.

Make transform manipulators of multiple types work together nicely

Some cleanups/refactors for transform manipulators

Add missing file

Implement new resize manipulators

clean up in cmake setup

small clean up

refactored manta liquid script

no need to rename main() from mantaflow - simply remove file from cmake and no main() method clash will occur

forgot to revert my own version number changes for macos in CMakeLists - fixed that

new:Collada 2 initial setup (added new subfolder, changed CMakelists, added collada version switcher to SPACE Menu

Add preview to Action datablock.

Hopefully did not forget anything.

Some UI access to multi-frames icons...

Not so happy to have to change whole UI API like that, but... can't
really see another solution, since layout API does not return any
handler to button(s) it creates. :/

Add first basic RNA API for multi-frames previews.

Not much to say here, still more to add, but this should be enough for a
first basic usage.

Multi-previews: basics (not yet usable from end-user code).

This commits adds data and basic API needed to handle multi-previews in
a single PreviewImage struct.

Data model is designed to be fully compatible (backward and forward)
with previous one, while keeping a 'flat array' design to store
previews. It also adds an extra integer per frame, that may be used to
store various meta-data.

This commit also updates write/read code, and adds basic BKE API to handle
multiple frames.

TODO: UI code (only very minimal stuff done so far, probably want to add
some template options too...). Access between icon ID and preview frames
is not yet fully designed, but think will rather go with an extra
integer rather that generating an icon ID/icon struct for every frame.

Use more modern OpenGL for dial manipulator drawing

Added a new shader for drawing with clipping plane.

Merge branch 'blender2.8' into transform-manipulators

Cycles: Begin implementing host side of CPU split kernel

Doesn't do anything yet, just getting things started.

Cycles: Add debug flags to control usage of split kernel for CPU devices
