Allow pasting between similar properties with different numbers of dimensions

When copying keyframes from a layer’s Scale property and pasting them to a shape’s Scale property, AE returns an error:

After Effects (Beta) error: The paste cannot be completed. Please check the copy and paste is between similar types of properties.

Details: The clipboard contains data with a different number of dimensions (3) than the paste target requires (2). ( 26 :: 269 )

While correct, it’s not intuitive. It would be helpful if, when copy-pasting from a 3-dimensional property to a related 2-dimensional property, the third dimension is ignored. Conversely, if copy-pasting from a 2- dimensional property to a related 3-dimensional property, paste in the first and second dimensions, and retain the existing third dimension already set on the property.
