[XeTeX] Support request for /Rotate in pdf

Hi Zdenek,

Many thanks to your clear explanation.

In my opinion, pdf with /Rotate should be rotated:
that means the orientation intended for screen
preview should be used. It seems pdfTeX is the
effective 'standard', and it intends to rotate such pdf,
and xdvipdfmx says "not supported yet" (it seems
the author of xdvipdfmx would like to rotate in the
future).

That may be true (I also know "pre-treatment" of pdf
I've mentioned before works well), but *normal* users
who are not familiar with pdf specification would be
confused:
  I carefully rotated pdf before inclusion, but XeTeX
  does not understand. Why?
Related questions have appeared in StackExchange
several times as I mentioned, so it seems natural that
normal users cannot understand the reason why
XeTeX includes some pdf figures in different orientation
from what viewers show.

Above is my personal opinion as a normal user.
I'd like to hear some other opinions.
Has anyone ever had same kind of questions?

Thanks,
Hironobu
