Where can I see the "official" texts of BIP 100 and 102?
BIP 102 was submitted as Pull Request, which you can see here: https://github.com/bitcoin/bitcoin/pull/6451

The latest draft of BIP 100 that I could find was here:
http://gtf.org/garzik/bitcoin/BIP100-blocksizechangeproposal.pdf
but it might be out of date.
