Fix for particle texture influence bug causing undefined (nan) values: When using a texture with "Particles/Strands" coordinates that in turn has a "Lifetime" influence on the particles, the texture eval
accesses the particle lifetime/dietime data before it is actually defined! This is a design flaw, but to avoid corrupted data for now just initialize the lifetime/dietime values for particles in advance
before evaluating the texture.
