	I tested this file with MegaPOV 0.5a and POV-Ray 3.1g (when all
the photon-related stuff is commented out).

	Linux RedHat 6.1 (2.2.12-20smp) :
	- MegaPOV crashed at the point described above.
	- POV works fine with official compile (static libpng ?) and
unofficial compile with dynamic libpng.

	SGI IRIX 6.5 :
	- both works (POV is unofficial compile)

	Digital UNIX V4.0F :
	- MegaPOV Floating exception when starting render (X display is open)
so it is again something different (I didn't trace that crash yet).
	- POV works (unofficial compile)

	Guess what ? Needs some works around ;-)

	BTW, ton boulot sur PvMegaPOV est super, mais je n'ai malheureusement
jamais pu installer PVM sur nos machines (suis pas root). Quid d'une version
MPI ? {hehehehe}
