Subject: Unofficial version requirement bug with julia_fractal?

I haven't tried with the latest, but at least with megapov 0.5a if I try
to make a julia_fractal like:
julia_fractal
{ <.1,.2,-.3,.4>
quaternion sqr
max_iteration 5
slice <1,1,1,1>, 0
}
megapov says:
error: This feature requires MegaPov 0.3.
Specify '#version unofficial MegaPov 0.5;' IN THIS FILE to enable this feature.
It should not require it because it works in the official povray.

):_;i&&_>1;printf("%s",_-70?_&1?"[]":" ":(_=0,"\n")),_/=2);} /*- Warp -*/

In Parse_Julia_Fractal (parse.c):
There's a conflict in the MegaPOV code between the original 'sqr' item
and another one added by Chris Huff for the "Noise3DCubeSqrHatPatch" and
isosurfaces. Code is missing in here to handle the official use of 'sqr'.
So consider it as a bug - sorry but no time today to fix it :_(

I forgot to mention: this is in MegaPOV 0.5a and cannot be sure this
problem is also in 0.6 (I didn't download source code yet).

You are right, we will change it for MP 0.6a.

Confirmed, I encountered this bug about a week ago when I played with
some julias (someone required a croissant :) ) but just worked around
it and forgot to report it to Nathan. It's the 'sqr' that confuses the
parser, prolly has something to do with the function parser.
