[x3d-public] Switching from Color to ColorRGBA using Alias node

[John Carlson]

Would it be possible to create an Alias node which copied its node type
from the node referenced in it’s USE field?   What I’m thinking of is
making rapid changes between types in an authoring tool.   I can already
accomplish it in a text editor.

Maybe I need to get more familiar with authoring tools?
