#36 graph postscript relief problems

[Harvey Davies]

The following two (very similar) examples generate
postscript with relief (defined by black lines) which
should not be there (and does not appear on the
screen):

Example 1.

package require BLT
blt::graph .g -plotborderwidth 0 -background white
.g element create x -xdata {0 1} -ydata {4 5} -symbol
""
.g legend configure -hide 1
pack .g
file delete g.ps
.g postscript output g.ps

Example 2.

package require BLT
blt::graph .g -plotrelief flat -background white
.g element create x -xdata {0 1} -ydata {4 5} -symbol
""
.g legend configure -hide 1
pack .g
file delete g.ps
.g postscript output g.ps

The problem did not exist in version 2.4u, but does
occur in versions 2.4w & 2.4x. I have not tried 2.4v. I
have tried both Windows & Unix & they both have the
problem.
