Particle emitter volume mode and grid mode broken in 2.75.x
Closed, ResolvedPublic

Description

System Information
OSX 10.10.3 NVidia 780m

Blender Version
Broken: (example: 2.75.x Release Candidate and dailies)
Worked: (2.74 Site Download)

When creating a particle system and selecting Volume Mode AND Grid Mode and let's say a cube as particle object,
the cubes don't fit inside the particle system's mesh. It shows a 3d grid of particle objects to form a cube..

Saving the file in 2.75 and reopening in 2.74 shows the erratic positioning, but after switching from another mode, back to Volume Mode, shows correct behaviour

@Campbell Barton (campbellbarton), do we consider this a stopper for the release?

@Sergey Sharybin (sergey):
I think that the correction does not work definitely in new nependency graph.
version 2.75 (sub 2), branch b'master', commit date b'2015-07-01' b'19:48', hash b'b05cf04', b'Release'

@perfection cat (sindra1961), it's on a TODO to revisit integration of particles into the new dependency graph. Old one has too much hacks around to keep particles working.
