forgot to fix psx11.c and devPicTeX.c while I was at it (devPicTeX.c
doesn't seem to change the color). Should psx11.c be devpsx11.c? Diffs:

/* Possibly Filled Rectangle */
static void PicTeX_Rect(double x0, double y0, double x1, double y1, int bg,
int fg)
{
+ SetLinetype(GP->lty);
PicTeX_MoveTo(x0, y0);
PicTeX_LineTo(x1, y0);
PicTeX_LineTo(x1, y1);
A less trivial question about setting line widths: in X, the same call
(XSetLineAttributes) sets both line type and line width. In PostScript
there are two separate calls.
The following quick hack to SetLinetype() appears to work pretty well
for X11, although there may be a better way to do it (logically,
SetLinetype ought to take both lty and lwd as arguments, or there should
be a separate SetLinewidth -- however, if there were two functions each
would have to look at least briefly at the current settings so as not to
screw them up):
Before doing this in PostScript (where the width and type are set in
separate calls), I'd like advice.
Also, is there a particular reason that default line width in PostScript
is 0.75 and not 1.0?
