The internal "parse_bounding_box" will read any (signed) value, integer
or float, as it should. But the PSPIC-macro will bail out silently if one
of the bounding box values is zero. I suggest changing line 21 of the
tmac.pspic macro from
    .if (\\n[llx] & \\n[lly] & \\n[urx] & \\n[ury]) \{\
to
    .if (\\n[llx] : \\n[lly] : \\n[urx] : \\n[ury]) \{\

This will let the macro proceed if at least one value is non-zero.
