Little round tinted 'dictator' glasses! Again!

I've just seen the TV adaptation of Terry Pratchett's The Colour of Magic / The Light Fantastic, and was amused to see that they'd given Vetinari (just called 'The Patrician'in this story) the inevitable little round tinted 'dictator' glasses. If you don't know the books, Vetinari is a sort of goodie - Pratchett described him as a mixture of 'Robespierre and Machiavelli', but I think he meant that in a good way - but I haven't noticed any mention of little round tinted dictator glasses in the books...
