Comment 10 for bug 1379777

@Laurie

This bug is about enabling apps to tell the shell what orientations it supports (through that desktop file parameter). The shell deciding when to rotate them.

What you want is the ability for an application to tell its current preferred orientation (at runtime), which overrides shell's decision on rotating an app (among its supported orientations) based on the device physical position etc.

So this is a different topic and it's being tracked on https://bugs.launchpad.net/mir/+bug/1382209
