Undo rev 14242, 14243, 14256, 14257: apparently our Perl for windows doesn't
support the open pragma. (OOPS: commited more than I wanted to. Also added files from the generic package 'shade'. This package was 'added' in r14213.) git-svn-id: svn://tug.org/texlive/trunk@14264 c570f23f-e606-0410-a88d-b1316a301751

+A `frequently asked question' is that for possibilites to produce
+shaded boxes.
+
+Since the answers usually (just as recently) point either to PostScript
+\special's and PiCTeX it seems that a `simpler' and easier to use version
+is not readily available --- though I did not check this.
+
+A small and simple approach to shaded boxes is the use of a special font
+providing shaded rectangles, and some macros which automatically compose the
+desired box from these characters.
+
+Since, of course, the finest shading can be achieved by using single pixels
+for the pattern, the best shading pattern is *device dependent*.
+Furthermore, one generally defined shading pattern would imply the danger,
+that - because of rounding errors - at the boundaries (between two of the
+characters) `lines' would occur, and that the pattern would not look completely
+uniform. Consequently, since different fonts are to be used for different
+printers, the dvi file is *device dependent* in this sense, too, though the
+code - both for the macros and for the metafont description - is device
+independent.

+
+{\tt SHADE} is a \TeX\ tool that can be used to produce shaded boxes
+neither using PostScript nor Pic\TeX.
+
+% The syntax is:
+
+\shade{This text will appear on a shaded background!}
+
+The shading macro first packs its argument into an hbox.
+
+\shade{\vbox{\hsize 5cm
+ \leftskip=0pt plus 1fil\rightskip=0pt plus 1fil
+ \parfillskip=0pt
+ Then it measures the dimensions of this box and produces a
+ shaded box slightly larger then this box, using the font
+ shade produced by {\tt shade.mf}. Finally it
+ puts the box back and overlays it with the shaded box.
+ \par
+ }}
+
+Since the best shading is achieved at the lowest possible resolution,
+the font \shade{SHADE} is {\bf not device independent} --- it uses
+the printer resolution. Therefore the .dvi file is
+{\bf not device independent}, either.
+The macro code, however, {\bf is device independent}.
+This method was used because otherwise shading, and in particular
+the boundaries between two shading characters, could turn out to be not
+completely uniform.
+For the same reason, the font should only be used at its true size.
+
+The {\tt shade} package consists of three files:
+ {\tt shade.mf, % MetaFont file for shading font
+ shade.tex, % macro file be used with LaTeX, too
+ shade.rdm. % this file
+ % it can be processed by TeX as a demo file
+ }
+It was tested with a HP Laserjet II plus.
