Morph angle
===========
**Syntax**:(morphangle float) Smoothly rotate the image to another angle. By
default rotation causes recalculation of the whole screen. To avoid this you
need to enable :ref:`fast rotate mode <rotate>`. Don't forget to disable it
later, since it slows down other animations.
A simple "rotozooming" animation::
(initstate)
(fastrotate #t)
(morphview -1.64128273713 -5.50393226816E-05 9.69332308848E-08 9.69332308834E-08)
(morphangle 300)
(usleep 10000000)
(wait)
(fastrotate #f)
**Available as**: command
