Subject: Skip TrueType font output for PS/PDF until it handles vertical
 layout.

The TrueType font subsetting code fails to emit VHEA/VMTX headers for the
font, so WMode 1 doesn't work to switch to vertical metrics. Added a bug
about this, and changed the PS/PDF output code to just use Type3 in this
case until the bug is fixed. Updated the reference images to match the
output for PDF/PS backends for the vertical font check.

 This needs a new testcase.

+
+Text drawn with vertical metrics cannot currently use TrueType
+subsetting for PDF/PS output as the code doesn't write out the necessary
+VHEA or VMTX entries to the TrueType font objects. As a result, cairo uses
+Type3 fonts which generates slightly different outlines.
