But how do we get them? I am not aware of any data structures that 
would allow us to find out which fonts are substituted in a particular 
document. I do not think we can afford to scan the complete document 
each time the dropdown list is opened because this is probably too 
slow, so we need to add an appropriate data structure to the document 
class to keep track of substituted fonts.
