Comment 4 for bug 1130349

For this particular bug we don't need additional libhud-qt support. This is all about HUD UI requiring an additional preview step on the phone for all live preview actions before sending COMMIT. The application does not need to care at this point about the fact that the screen is too small for the live preview to be visible. The live preview is still being updated behind the HUD just as it should.

We have plans to enable the applications to specify for each actions if they can support live preview or even explicitly require an additional preview step, but that is an another matter.
