Hmm... the conversion ops don't seem to be working for me, in that case. I did look for an existing alternative, though not in the source. If it's just some issue on my end (which it appears to be, given the time of that commit), I'll work it out.
Edit: Alright, I'm real lost now... The casts are not working for me, and VS's Object Browser doesn't show any casting operators in any of the Vector classes (see attached). Given the state of the GitHub codebase, it's possible that this is the result of an older version of the software being available on the "download" section of the website. Can anyone confirm this?
Edited edit: Cast works fine after recompiling the source on GitHub. Should I be worried at all about using the csfml libraries that come with the download on the main SFML site?
(This should probably be migrated to the appropriate "help" section)
