Ah, just without protocol. Thanks! Any documentation how exactly the
fact that we have direct shader source code is detected?

I just added this to view3dscene. URL is recognized as direct shader
source if it doesn't start with any protocol *and*
has some newlines (needed to recognize relative URLs without protocol
correctly).
