/* 			PSL: PostScript Light (Fortran Binder)
 * PSL is a library of plot functions that create PostScript.
 * All the routines write their output to the same plotting file,
 * which can be dumped to a Postscript output device (laserwriters).
 * PSL can handle and mix text, line-drawings, and bit-map graphics
 * in both black/white and color.  Colors are specified with r,g,b
 * values in the range 0-1.
 *
 * PSL conforms to the PostScript Files Specification V 3.0.
 *
 * FORTRAN considerations:
 *	All floating point data are assumed to be DOUBLE PRECISION
 *	All integer data are assumed to be a long INTEGER, i.e. INTEGER*8
 *
 *	When passing (from FORTRAN to C) a fixed-length character variable which has
 *	blanks at the end, append '\0' (null character) after the last non-blank
 *	character.  This is so that C will know where the character string ends.
 *	It is NOT sufficient to pass, for example, "string(1:string_length)".
 *
 * List of API functions:
 * PSL_beginaxes
 * PSL_beginclipping	: Clips plot outside the specified polygon
 * PSL_beginlayer	: Place begin object group DSC comment.
 * PSL_beginplot	: Initialize parameters for a new plot.
 * PSL_beginsession	: Creates a new PSL session
 * PSL_endaxes		: Turns off mapping of user coordinates to PS units
 * PSL_endclipping	: Restores previous clipping path
 * PSL_endlayer		: Place end object group DSC comment.
 * PSL_endplot		: Close plotfile
 * PSL_endsession	: Terminates the PSL session
 * PSL_plotarc		: Plots a circular arc
 * PSL_plotaxis		: Plots an axis with tickmarks and annotation/label
 * PSL_plotbitimage	: Plots a 1-bit image or imagemask
 * PSL_plotcolorimage	: Plots a 24-bit 2-D image using the colorimage operator
 * PSL_plotepsimage	: Inserts EPS image
 * PSL_plotline		: Plots a line
 * PSL_plotparagraph	: Plots a text paragraph
 * PSL_plotparagraphbox	: Plots a box beneath a text paragraph
 * PSL_plotpoint	: Absolute or relative move to new position (pen up or down)
 * PSL_plotpolygon	: Creates a polygon and optionally fills it
 * PSL_plotsegment	: Plots a 2-point straight line segment
 * PSL_plotsymbol	: Plots a geometric symbol and [optionally] fills it
 * PSL_plottext		: Plots textstring
 * PSL_plottextbox	: Draw a filled box around a textstring
 * PSL_plottextclip	: Place clippaths to protect areas where labels will print
 * PSL_plottextpath	: --"-- for curved text following lines - also places labels
 * PSL_loadimage	: Read image file of supported type
 * PSL_command		: Writes a given PostScript statement to the plot file
 * PSL_comment		: Writes a comment statement to the plot file
 * PSL_setcolor		: Sets the pen color or pattern
 * PSL_setdefaults	: Change several PSL session default values
 * PSL_setdash		: Specify pattern for dashed line
 * PSL_setfill		: Sets the fill color or pattern
 * PSL_setfont		: Changes current font and possibly reencodes it to current encoding
 * PSL_setformat	: Changes # of decimals used in color and gray specs [3]
 * PSL_setlinecap	: Changes the line cap setting
 * PSL_setlinejoin	: Changes the line join setting
 * PSL_setlinewidth	: Sets a new linewidth
 * PSL_setmiterlimit	: Changes the miter limit setting for joins
 * PSL_setorigin	: Translates/rotates the coordinate system
 * PSL_setparagraph	: Sets parameters used to typeset text paragraphs
 * PSL_setpattern	: Sets up a pattern fill in PS
 * PSL_defpen		: Encodes a pen with attributes by name in the PS output
 * PSL_definteger	: Encodes an integer by name in the PS output
 * PSL_defpoints	: Encodes a pointsize by name in the PS output
 * PSL_defcolor		: Encodes a rgb color by name in the PS output
 * PSL_deftextdim	: Sets variables for text height and width in the PS output
 * PSL_defunits:	: Encodes a dimension by name in the PS output
 *
