[Bf-committers] sequence.c

In reply to Shaul Kedem (shaul.kedem at gmail.com):

Well looking at the code it looks like
nr = the part of the strip we want data for.  (Call it frame)
se+= nr;  Jumps to the part we want.
se->nr = nr;  I'm guessing is to give it its "Frame" #
	I'm guessing some other code uses it.
