Implement camera code.  The orientation detection was messy.
I think this was a wrong way.
Reworked with Camera app Intent.
It works with a thumbnail (150x200, 150x240, 180x300, etc.) sized
pictures, but to get a full size images, I leaned that there are a lot
of _variations_ I need to take care of; yet another android
divergence...
