+/* the following notes use the following conventions:
+SCREEN LEFT				SCREEN RIGHT
+in this file and maskbits.c, left and right refer to screen coordinates,
+NOT bit numbering in registers.
+
+starttab[n]
+	bits[0,n-1] = 0	bits[n,PLST] = 1
+endtab[n] =
+	bits[0,n-1] = 1	bits[n,PLST] = 0
+
+startpartial[], endpartial[]
+	these are used as accelerators for doing putbits and masking out
+bits that are all contained between longword boudaries.  the extra
+256 bytes of data seems a small price to pay -- code is smaller,
+and narrow things (e.g. window borders) go faster.
+
+the names may seem misleading; they are derived not from which end
+of the word the bits are turned on, but at which end of a scanline
+the table tends to be used.
+
+look at the tables and macros to understand boundary conditions.
+(careful readers will note that starttab[n] = ~endtab[n] for n != 0)
+
+-----------------------------------------------------------------------
+these two macros depend on the screen's bit ordering.
+in both of them x is a screen position.  they are used to
+combine bits collected from multiple longwords into a
+single destination longword, and to unpack a single
+source longword into multiple destinations.
+
+SCRLEFT(dst, x)
+	takes dst[x, PPW] and moves them to dst[0, PPW-x]
+	the contents of the rest of dst are 0.
+	this is a right shift on LSBFirst (forward-thinking)
+	machines like the VAX, and left shift on MSBFirst
+	(backwards) machines like the 680x0 and pc/rt.
+
+SCRRIGHT(dst, x)
+	takes dst[0,x] and moves them to dst[PPW-x, PPW]
+	the contents of the rest of dst are 0.
+	this is a left shift on LSBFirst, right shift
+	on MSBFirst.
+
+
+the remaining macros are cpu-independent; all bit order dependencies
+are built into the tables and the two macros above.
+
+maskbits(x, w, startmask, endmask, nlw)
+	for a span of width w starting at position x, returns
+a mask for ragged bits at start, mask for ragged bits at end,
+and the number of whole longwords between the ends.
+
+maskpartialbits(x, w, mask)
+	works like maskbits(), except all the bits are in the
+	same longword (i.e. (x&PIM + w) <= PPW)
+
+maskPPWbits(x, w, startmask, endmask, nlw)
+	as maskbits, but does not calculate nlw.  it is used by
+	mfbGlyphBlt to put down glyphs <= PPW bits wide.
+
+-------------------------------------------------------------------
+
+NOTE
+	any pointers passed to the following 4 macros are
+	guranteed to be PPW-bit aligned.
+	The only non-PPW-bit-aligned references ever made are
+	to font glyphs, and those are made with getleftbits()
+	and getshiftedleftbits (qq.v.)
+
+	For 64-bit server, it is assumed that we will never have font padding
+	of more than 4 bytes. The code uses int's to access the fonts
+	intead of longs.
+
+getbits(psrc, x, w, dst)
+	starting at position x in psrc (x < PPW), collect w
+	bits and put them in the screen left portion of dst.
+	psrc is a longword pointer.  this may span longword boundaries.
+	it special-cases fetching all w bits from one longword.
+
+	+--------+--------+		+--------+
+	|    | m |n|      |	==> 	| m |n|  |
+	+--------+--------+		+--------+
+	    x      x+w			0     w
+	psrc     psrc+1			dst
+			m = PPW - x
+			n = w - m
+
+	implementation:
+	get m bits, move to screen-left of dst, zeroing rest of dst;
+	get n bits from next word, move screen-right by m, zeroing
+		 lower m bits of word.
+	OR the two things together.
+
+putbits(src, x, w, pdst)
+	starting at position x in pdst, put down the screen-leftmost
+	w bits of src.  pdst is a longword pointer.  this may
+	span longword boundaries.
+	it special-cases putting all w bits into the same longword.
+
+	+--------+			+--------+--------+
+	| m |n|  |		==>	|    | m |n|      |
+	+--------+			+--------+--------+
+	0     w				     x     x+w
+	dst				pdst     pdst+1
+			m = PPW - x
+			n = w - m
+
+	implementation:
+	get m bits, shift screen-right by x, zero screen-leftmost x
+		bits; zero rightmost m bits of *pdst and OR in stuff
+		from before the semicolon.
+	shift src screen-left by m, zero bits n-PPW;
+		zero leftmost n bits of *(pdst+1) and OR in the
+		stuff from before the semicolon.
+
+putbitsrop(src, x, w, pdst, ROP)
+	like putbits but calls DoRop with the rasterop ROP (see mfb.h for
+	DoRop)
+
+putbitsrrop(src, x, w, pdst, ROP)
+	like putbits but calls DoRRop with the reduced rasterop ROP
+	(see mfb.h for DoRRop)
+
+-----------------------------------------------------------------------
+	The two macros below are used only for getting bits from glyphs
+in fonts, and glyphs in fonts are gotten only with the following two
+mcros.
+	You should tune these macros toyour font format and cpu
+byte ordering.
+
+NOTE
+getleftbits(psrc, w, dst)
+	get the leftmost w (w<=32) bits from *psrc and put them
+	in dst.  this is used by the mfbGlyphBlt code for glyphs
+	<=PPW bits wide.
+	psrc is declared (unsigned char *)
+
+	psrc is NOT guaranteed to be PPW-bit aligned.  on  many
+	machines this will cause problems, so there are several
+	versions of this macro.
+
+	this macro is called ONLY for getting bits from font glyphs,
+	and depends on the server-natural font padding.
+
+	for blazing text performance, you want this macro
+	to touch memory as infrequently as possible (e.g.
+	fetch longwords) and as efficiently as possible
+	(e.g. don't fetch misaligned longwords)
+
+getshiftedleftbits(psrc, offset, w, dst)
+	used by the font code; like getleftbits, but shifts the
+	bits SCRLEFT by offset.
+	this is implemented portably, calling getleftbits()
+	and SCRLEFT().
+	psrc is declared (unsigned char *).
