[Bf-python] RenderEngine API - fractional frame

[Matt Ebb]

It's really on a case by case basis... Hair stuff is a bit of a minefield
with some things supported (accessible in RNA) and some not. I think for
dynamics alone though, it might work - I recall I got some basic tests
working ok for at least integer frame motion blur in my renderman exporter,
but I'm not 100% sure about fractional frames.

Part of the problem is that the point cache code in blender used for this
physics stuff has really patchy support for fractional frames, and from
memory it is different for if the sim is cached or not, too.

I guess you'll have to try it and see.
