Hugo Locurcio 84076513b1
Use global coordinates for particles by default 
Particles won't move or rotate anymore with the node (or its parents)
by default. This new default behavior is generally more suited
to most use cases. Local coordinates can still be enabled on a per-node basis.

This affects both 2D and 3D particles, and both CPU and GPU-based particles.
