Frame System

[Andreas Zehender]

IMO these defines should never make it into the povray code for 
rendering, we would be to inflexible here. All animated 
object/properties should be calculated for a single frame, exported to 
povray and rendered.

I tell you why:
If we get scripting inside kpovmodeler, we could not only base 
properties on the clock value, but also on properties of other objects. 
Say, there is a sun system with 4 planets or asteroids that rotate 
around the sun and interact with each other with their gravitation. Such 
a system can be calculated quite easy in discrete steps.
Or the "export to povray" property: Objects could be visible only in 
some frames. That all would be incredible difficult with the povray defines.

I think there is already some scripting support in KDE. Will look deeper 
into that...

Regards,
Andreas
