LANPR: Auto update GPencil when in other engines.

GPencil: Use alpha component for converting splines

The alpha channel was not used before.

Note: This is a previous step before changing svg add-on to support alpha.

Merge remote-tracking branch 'origin/greasepencil-object' into soc-2019-npr

LANPR: GPU mode batch refresh method changes.

Merge remote-tracking branch 'origin/master' into sybren-usd

utility to map multiple sockets

GPencil: Cleanup MSVSC warnings

construct SmallVector from arbitrary containers

more general function tree dependency discovery

USD: Fixed issue with mesh particle export

When mesh particles were exported, the object name was still used for each
instance of that object. As such, only one instance was written to USD.
This is now fixed by suffixing the object name with the particle's
persistent ID, giving each particle XForm a unique name.

Particles are still only written when they are alive, which means that they
are always visible (there is currently no code that deals with marking them
as invisible outside their lifespan).

GPencil: Improve curve conversion when end points are very near

When the distance between first and last point of the curve was very small, there was a glitch in the join. Now the points are moved slightly to get good result.

USD: Fixed bug getting evaluation mode property

more powerful custom emitter

remove unnecessary check

fix bug in fgraph tuple call

GPencil: Improve Close stroke function for very small gaps

When the gap is very small, don't need to add new points to the stroke, just cyclic.

GPencil: Create one stroke for each spline

For curves with several splines, must create a stroke for each of them or the shape would be wrong.

USD: Make USD_PATH configurable via a CMake variable

The default is still `USD_PATH=/opt/usd`, and using USD still requires you
to manually install USD without Python bindings.
