Native map text
I imagine CSS3-type support would be damn-near impossible with this system lol.
The internal (windows) implementation of valign=bottom actually does trim excess text from the top, but I figured it was more convenient to trim from the bottom (thinking in terms that for a single-output, it's better to see the beginning then the end, but either way you lose text so it's probably not a big deal). I can change ours to match so we can at least try it out.
Just make sure you truncate your text after some point, because you really don't want to be setting maptext to huge strings that are 90% truncated.
