Changes: Do not show black window on rotation
Changes: Do not show black window on rotation

Fixes: NB#261125 - blanking and unblanking with pwr key at note view
editor's landscape mode results blank screen for movement.

Details: Do not try to do a rotation animation when there is no initial
pixmap available. This could happen when show and rotation happens at
the exact same time.
