[XeTeX] xdvipdfmx doesn't seem to respect PDF crop areas

Formally higher version will be allowed by rewriting the function
pdf_set_version() in pdfobj.c like

static unsigned pdf_version = 4;
void pdf_set_version (unsigned version)
{
  if (version >= 2 && version <= 7) {
    pdf_version = version;
  }
}

Please note the option [dvipdfm]:
\documentclass[dvipdfm]{article}
... ...


If you set the [dvipdfm] option as above, compilation itself
by xelatex must fail if foo.bb is missing.
