image_transform_cycle.lua

-- image_transform_cycle
-- @short: Toggle transform cycles ON/OFF.
-- @inargs: vid, toggle
-- @outargs:
-- @longdescr: The default behavior for objects with one or several
-- transforms queued is to drop all tracking of a transform state
-- after it has been completed. This function changes that behavior
-- to instead requeue the transform at the end of the chain,
-- looping the animation.
-- @note: Since this makes a lot of the object state variable,
-- this function has a severe impact on the ability to cache previous
-- states and can thus be very expensive.
-- @group: image
-- @cfunction: cycletransform
