My undergraduate degree (in pure mathematics, completed a mere 17 years
ago) covered the last 5 topics in decent depth, and half of the first
topic, but no projective geometry. And in fact, the proofs were based
on exactly the tools you mention

which were all covered (yes, even homological algebra) in those
undergraduate courses. And this was at the University of Waterloo, and
my colleagues who graduated from Berkeley, Harvard, Oxford and the Ecole
Polytechnique generally covered even more, although my colleagues from
less-renowned universities covered less.
I guess the only useful conclusion from this is: *which* undergraduate
education in mathematics are you using as your standard? The
``average'' american university, or what gets taught in the top 25 math
programs in the world? I suspect the answer will be /wildly/ different.
