+% font ISOEncode font
+% This procedure changes the encoding of a font from the default
+% Postscript encoding to ISOLatin1.  It's typically invoked just
+% before invoking "setfont".  The body of this procedure comes from

+% StrokeClip
+%
+% This procedure converts the current path into a clip area under
+% the assumption of stroking.  It's a bit tricky because some Postscript
+% interpreters get errors during strokepath for dashed lines.  If
+% this happens then turn off dashes and try again.

+% desiredSize EvenPixels closestSize
+%
+% The procedure below is used for stippling.  Given the optimal size
+% of a dot in a stipple pattern in the current user coordinate system,

+% pixel size.  This allows stipple patterns to be displayed without
+% aliasing effects.

+% width height string StippleFill --
+%
+% Given a path already set up and a clipping region generated from
+% it, this procedure will fill the clipping region with a stipple
+% pattern.  "String" contains a proper image description of the
+% stipple pattern and "width" and "height" give its dimensions.  Each
+% stipple dot is assumed to be about one unit across in the current
+% user coordinate system.  This procedure trashes the graphics state.

+% x y strings spacing xoffset yoffset justify stipple DrawText --
+% This procedure does all of the real work of drawing text.  The

+% following arguments must be on the stack:
+%
+% x, y -	Coordinates at which to draw text.
+% strings -	An array of strings, one for each line of the text item,
+%		in order from top to bottom.
+% spacing -	Spacing between lines.
+% xoffset -	Horizontal offset for text bbox relative to x and y: 0 for
+%		nw/w/sw anchor, -0.5 for n/center/s, and -1.0 for ne/e/se.
+% yoffset -	Vertical offset for text bbox relative to x and y: 0 for
+%		nw/n/ne anchor, +0.5 for w/center/e, and +1.0 for sw/s/se.
+% justify -	0 for left justification, 0.5 for center, 1 for right justify.
+% stipple -	Boolean value indicating whether or not text is to be
+%		drawn in stippled fashion.  If text is stippled,
+%		procedure StippleText must have been defined to call
+%		StippleFill in the right way.
+%
+% Also, when this procedure is invoked, the color and font must already
+% have been set for the text.
