Color	Colors are linearly interpolated between the two key frames. Color interpolation may include interpolation of transparency using a Bezier to provide more natural fade-in/fade-out
Size	Linear interpolation of numerical values (usually sizes) between the two key frames.
Transparency	Linear interpolation of transparency values
ObjectPosition	Special interpolator for changes in label and custom graphics positions. Doesn’t support changes in justification or object anchor.
Position	Linearly interpolate changes in X,Y position of objects
Crossfade	For properties that can not be easily interpolated (e.g. node shape), fades the object out, then fades it in with the new property
CustomGraphicsCrossfade	Crossfade between two custom graphics.
Visible	Fades an object in or out if the visibility changes
None	This visual attribute is not interpolated.
