Application needs to specifically request portrait mode with a window
property (I guess there's some API for that), otherwise window manager
uses landscape mode for the application window.

App can listen to standard XRandr messages for this transition if
it wants to, but it's not necessary.

It's just a question whether your distro's Xephyr version has XRandR
enabled.  It should.

Then just use "xrandr -o <left/right/normal>" for Xephyr's display.
