     PlotPar - set plot parameters

SYNOPSIS
     PlotPar expr expr expr expr expr
         ( 0 | 1 ) ( 0 | 1 ) ( 0 | 1 ) ( 0 | 1 )
         expr expr expr

DESCRIPTION
     Set size and options for plots. The first argument
     gives the width of the paper, the second one the
     height. The third argument gives the width of the
     plot, the fourth one the height. If one of the plot
     sizes is 0, it is calculated to correspond to the
     dimensions (aspect ratio) of the window. The plot
     is centered on the paper.

     The current unit for these sizes is shown in the
     prompt, it can be changed with the PlotUnit command.
     The default paper size also depends on the current
     unit.

     The fifth argument selects the horizontal resolution
     used for saving image (TIFF, JPEG, PNG) files.

     The first option switches stereo plotting on or off.

     The second option switches shading and hidden surface
     elimination for the plot. The third only has an
     influence if shading is switched on. If it is
     selected, a full hidden surface elimination is done.
     This can take a few minutes for complex plots, but it
     is necessary to produce perfect results as soon as the
     scene contains spheres, cylinders or primitives. If it
     is not selected, a simple depth sorting is used, which
     is much faster, but the result can contain slight
     errors. For important plots (publications), this
     option must always be switched on.

     The fourth option selects whether the plot is
     rotated by 90 degrees to produce a landscape plot.
     Note that the size of the plot (arguments 3 and 4)
     is still given in the original orientation of the
     plot, before rotation. The size of the paper is
     given in the orientation used by the printer, which
     is normally portrait. So e. g. good size for a
     landscape plot on A3 format are 29.7 42 0 26.

     The third but last parameter select the precision
     (resolution) of the plot. See DrawPrec for an
     explanation of this parameter.

     The second but last parameter selects a gamma correction
     parameter. 1.0 will leave the colors unchanged, values
     less than 1.0 will make the colors brighter, values
     greater than 1.0 will make the colors darker. Note
     that the "correct" gamma value depends on the output
     device used, so using gamma correction when producing
     the file is in principal not the right thing to do.
     We offer this possibilty for convenience sake, it is
     often difficult to do decent gamma correction on the
     output file (e. g. for PostScript) with other
     possibilities.

     The last parameter selects the quality for JPEG plots.
     Recommended values are between 50 (strong compression
     with reasonable quality) and 95 (excellent quality).
