Details:

When trying to print a figure that contains a hggroup with its "units"
property set to something other than "normalized", printing fails with the
following error:

error: invalid value = data
error: called from
    print at line 486 column 13


Example that produces this error:

hf = clf (figure (1));
hax = axes (hf);
hl = plot (hax, [0, 1]);
hg = annotation ("textbox", [0.5, 0.5, 0.1, 0.1], "String", "test");
set (hg, "Units", "pixels");

print (hf, "test_annotation_units.png");
