-/* 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 *).
