ok this can be done. I refrained from doing this in case macro sets
are tweaked and the glyph positions change slightly. Instead I
thought to use troff state machine assertions which are verified
by post-grohtml.

well not necessarily. When the assertion fails post-grohtml exits with
a non zero value and dejagnu records 1 test failure.

Yes, certainly the tests would become more extensive if they were
diff'ed against expected output. I think this is a good idea for the
troff low level tests - as this output should not change.. shall I
generate the relevant files?

The example directory simply builds, pic.html and webpage.html. The
test here is only questioning whether -Thtml can build these files
without crashing.  A limited but still useful test.
