[OpenLayers-Users] Layer.clone()

[Matt Williamson]

Chris,

Thanks for the reply. I'm willing to try and provide a patch, but I  
should probably make certain I'm making it do the right thing. So far,  
my assumptions are that a cloned layer should be identical to the  
source layer except for the following:

1. Should have a different, unique "id" property
2. Should have the "map" property cleared (as Layer.clone does, but  
Layer.Image.clone does not)

Anything else? You guys are far more familiar with the nuts and bolts  
than I am, so I don't know what other properties might need to be made  
unique or initialized.

-Matt
