/* Determine if animations are enabled or not. Using the -animator proxy will automatically set allowsImplicitAnimation to YES. When YES, other properties can implicitly animate along with the initially changed property. For instance, calling [[view animator] setFrame:frame] will allow subviews to also animate their frame positions. This is only applicable when layer backed on Mac OS 10.8 and later. The default value is NO.
