Does AIX support the Xrandr extension?

[Volker Simonis]

Hi AIX experts,

a recent change ("8210863: Remove Xrandr include files from JDK
sources" [1]) has removed the Xrander header files which were
previously checked in in the OpenJDK sources, from there. This means
that the build now requires the platform version of these header
files:

X11/extensions/Xrandr.h
X11/extensions/randr.h

To the best of my knowledge, AIX does not support the Xrandr extension
and I couldn't find the corresponding header files any where (even not
in the "AIX Toolbox for Linux Applications" [2]).

I've therefor prepared a change which fixes these issues on AIX (see:
http://mail.openjdk.java.net/pipermail/2d-dev/2018-November/009636.html).

However, before pushing this fix, I'd like to get a confirmation if
Xrandr is indeed not supported and not available on AIX. If it is,
please point me to a place where I can get a package with the
corresponding header files.

Thank you and best regards,
Volker
