void end_macroblock	(	Macroblock *	currMB,
		Boolean *	end_of_slice,
		Boolean *	recode_macroblock
	)

terminates processing of the current macroblock depending on the chosen slice mode

Check end-of-slice group condition first

Now check maximum # of MBs in slice

Check if the last coded macroblock fits into the size of the slice But only if this is not the first macroblock of this slice

(first MB OR first MB in a slice) AND bigger that maximum size of slice

MB that did not fit in this slice anymore is not a Skip MB

Parameters:

	currMB	Current Macroblock
	end_of_slice	returns true for last macroblock of a slice, otherwise false
	recode_macroblock	returns true if max. slice size is exceeded an macroblock must be recoded in next slice
