NBuff

Short:        Double bufferung routines example. V2.2
Architecture: m68k-amigaos

NBuff		Rewrite of A.C.R. Martin's original DBuff double-buffer
		routines from an early library disk.  No more memory leaks nor
		misuse of MrgCop()!  The JACOsub video titler uses NBuff.
		NBuff allows any number of video buffers, not just two.
		A single #define makes it fast and Intuition-unfriendly
		(like DBuff) or friendly (which is a bit slower).  Another
		#define controls whether NBuff will or will not use the Layers
		library for transparent, automatic buffer boundary clipping.
		Version 2.2, PD, C source + binary demo.  Docs in NBuff.c.
