+/* single-pixel lines on a color frame buffer
+
+ NON-SLOPED LINES
+ horizontal lines are always drawn left to right; we have to
+move the endpoints right by one after they're swapped.
+ horizontal lines will be confined to a single band of a
+region. the code finds that band (giving up if the lower
+bound of the band is above the line we're drawing); then it
+finds the first box in that band that contains part of the
+line. we clip the line to subsequent boxes in that band.
+ vertical lines are always drawn top to bottom (y-increasing.)
+this requires adding one to the y-coordinate of each endpoint
+after swapping.
+
+ SLOPED LINES
+ when clipping a sloped line, we bring the second point inside
+the clipping box, rather than one beyond it, and then add 1 to
+the length of the line before drawing it. this lets us use
+the same box for finding the outcodes for both endpoints. since
+the equation for clipping the second endpoint to an edge gives us
+1 beyond the edge, we then have to move the point towards the
+first point by one step on the major axis.
+ eventually, there will be a diagram here to explain what's going
+on. the method uses Cohen-Sutherland outcodes to determine
+outsideness, and a method similar to Pike's layers for doing the
+actual clipping.

+/*
+ * ==========================================================================
+ * Converted from mfb to support memory-mapped color framebuffer by smarks@sun,
+ * April-May 1987.
+ *
+ * The way I did the conversion was to consider each longword as an
+ * array of four bytes instead of an array of 32 one-bit pixels. So
+ * getbits() and putbits() retain much the same calling sequence, but
+ * they move bytes around instead of bits. Of course, this entails the
+ * removal of all of the one-bit-pixel dependencies from the other
+ * files, but the major bit-hacking stuff should be covered here.
+ *
+ * I've created some new macros that make it easier to understand what's
+ * going on in the pixel calculations, and that make it easier to change the
+ * pixel size.
+ *
+ * name explanation
+ * ---- -----------
+ * PSZ pixel size (in bits)
+ * PGSZ pixel group size (in bits)
+ * PGSZB pixel group size (in bytes)
+ * PGSZBMSK mask with lowest PGSZB bits set to 1
+ * PPW pixels per word (pixels per pixel group)
+ * PPWMSK mask with lowest PPW bits set to 1
+ * PLST index of last pixel in a word (should be PPW-1)
+ * PIM pixel index mask (index within a pixel group)
+ * PWSH pixel-to-word shift (should be log2(PPW))
+ * PMSK mask with lowest PSZ bits set to 1
+ *
+ *
+ * Here are some sample values. In the notation cfbA,B: A is PSZ, and
+ * B is PGSZB. All the other values are derived from these
+ * two. This table does not show all combinations!
+ *
+ * name cfb8,4 cfb32,4 cfb8,8 cfb32,8
+ * ---- ------ ------- ------ -------
+ * PSZ 8 32 8 32
+ * PGSZ 32 32 64 64
+ * PGSZB 4 4 8 8
+ * PGSZBMSK 0xF 0xF 0xFF 0xFF
+ * PPW 4 1 8 2
+ * PPWMSK 0xF 0x1 0xFF 0x3
+ * PLST 3 0 7 1
+ * PIM 0x3 0x0 0x7 0x1
+ * PWSH 2 0 3 1
+ * PMSK 0xFF 0xFFFFFFFF 0xFF 0xFFFFFFFF
+ *
+ *
+ * I have also added a new macro, PFILL, that takes one pixel and
+ * replicates it throughout a word. This macro definition is dependent
+ * upon pixel and word size; it doesn't use macros like PPW and so
+ * forth. Examples: for monochrome, PFILL(1) => 0xffffffff, PFILL(0) =>
+ * 0x00000000. For 8-bit color, PFILL(0x5d) => 0x5d5d5d5d. This macro
+ * is used primarily for replicating a plane mask into a word.
+ *
+ * Color framebuffers operations also support the notion of a plane
+ * mask. This mask determines which planes of the framebuffer can be
+ * altered; the others are left unchanged. I have added another
+ * parameter to the putbits and putbitsrop macros that is the plane
+ * mask.
+ * ==========================================================================
+ */
+
+/*
+ * PSZ needs to be defined before we get here. Usually it comes from a
+ * -DPSZ=foo on the compilation command line.
+ */
+
+/*
+ * PixelGroup is the data type used to operate on groups of pixels.
+ * We typedef it here to unsigned long with the assumption that you
+ * want to manipulate as many pixels at a time as you can. If unsigned
+ * long is not appropriate for your server, define it to something else
+ * before including this file. In this case you will also have to define
+ * PGSZB to the size in bytes of PixelGroup.

+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 ONLY IF
+ dst is UNSIGNED.
+ is cast as an unsigned.
+ this is a right shift on the VAX, left shift on
+ Sun 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 ONLY IF
+ dst is UNSIGNED.
+ this is a left shift on the VAX, right shift on
+ Sun and pc-rt.
+
+
+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 pixels at start, mask for ragged pixels at end,
+and the number of whole longwords between the ends.
+
+maskpartialbits(x, w, mask)
+ works like maskbits(), except all the pixels are in the
+ same longword (i.e. (x&0xPIM + w) <= PPW)
+
+mask32bits(x, w, startmask, endmask, nlw)
+ as maskbits, but does not calculate nlw. it is used by
+ cfbGlyphBlt to put down glyphs <= PPW bits wide.
+
+getbits(psrc, x, w, dst)
+ starting at position x in psrc (x < PPW), collect w
+ pixels 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 pixels, move to screen-left of dst, zeroing rest of dst;
+ get n pixels from next word, move screen-right by m, zeroing
+ lower m pixels of word.
+ OR the two things together.
+
+putbits(src, x, w, pdst, planemask)
+ 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 pixels, shift screen-right by x, zero screen-leftmost x
+ pixels; zero rightmost m bits of *pdst and OR in stuff
+ from before the semicolon.
+ shift src screen-left by m, zero bits n-32;
+ zero leftmost n pixels of *(pdst+1) and OR in the
+ stuff from before the semicolon.
+
+putbitsrop(src, x, w, pdst, planemask, ROP)
+ like putbits but calls DoRop with the rasterop ROP (see cfb.h for
+ DoRop)
+
+getleftbits(psrc, w, dst)
+ get the leftmost w (w<=PPW) bits from *psrc and put them
+ in dst. this is used by the cfbGlyphBlt code for glyphs
+ <=PPW bits wide.

+ *
+ * There are four possible operations on each bit in the destination word,
+ *
+ * 1 2 3 4
+ *
+ * 0 0 0 1 1
+ * 1 0 1 0 1
+ *
+ * On examination of the reduced rop equation (dst = (dst & and) ^ xor),
+ * these four fall to reduced rops as follows:
+ *
+ * and 0 1 1 0
+ * xor 0 0 1 1
+ *
+ * or, (if 'and' is expensive) (dst = (dst | or) ^ xor)
+ *
+ * or 1 0 0 1
+ * xor 1 0 1 0
+ *
+ * The trouble with using this later equation is that trivial
+ * rasterop reduction is more difficult; some common rasterops
+ * use complicated expressions of xor/and instead of the simple
+ * ones while other common rasterops are not made any simpler:
+ *
+ * GXcopy: *dst = ~xor instead of *dst = xor
+ * GXand: *dst = *dst & ~or instead of *dst = *dst & and
+ * GXor: *dst = *dst | or instead of *dst = *dst | xor
+ * GXxor: *dst = *dst ^ xor instead of *dst = *dst ^ xor
+ *
+ * If you're really set on using this second mechanism, the changes
+ * are pretty simple.
+ *
+ * All that remains is to provide a mechanism for computing and/xor values
+ * based on the raster op and foreground value.
+ *
+ * The 16 rops fall as follows, with the associated reduced
+ * rop and/xor and or/xor values. The values in parenthesis following the
+ * reduced values gives an equation using the source value for
+ * the reduced value, and is one of {0, src, ~src, 1} as appropriate.

+ compute at which row the glyph starts to be in it,
+ and at which row the glyph ceases to be in it
+ compute which is the first glyph inside the left
+ edge, and the last one inside the right edge
+ draw a fractional first glyph, using only
+ the rows we know are in
+ draw all the whole glyphs, using the appropriate rows
+ draw any pieces of the last glyph, using the right rows
+
+ this way, the code would take advantage of knowing that
+ all glyphs are the same height and don't overlap.
