Is the above text correct on all platforms? If it is not always MRI then how the user should use the icon? instanceof+cast? BTW an example does not show how to solve the bug itself, on how to access the "large icons".

Need to clarify: the implSpec is a part of the specification so can we point the non public "ShellFolder" class?

What are the "virtual pixels"? I remember we refer to something similar by the point in the "user space coordinate system" Or probably we use the virtual pixels somewhere?
