Respect minimum-scale and maximum-scale viewport properties
We should use the viewport-minimum-scale and viewport-maximum-scale metadata to limit default zoom and user-specified zoom. These metadata values are non-standard, but used by Mobile Safari and Android. They are documented here: http://developer.apple.com/safari/library/documentation/AppleApplications/Reference/SafariHTMLRef/Articles/MetaTags.html
This patch adds minimum-scale and maximum-scale support to the viewport sizing code, and adds several new test cases. Expected results are partly calculated rather than hard-coded so the tests work at different screen sizes (like under xmonad on my development machine). This patch does *not* use minimum- and maximum-scale to limit volume-button or gesture zooming. I think I'll file a separate bug+patch for that...
Bug 561815 filed for limits during volume-button/gesture zooming.

I love the testcases, but remember to set the in-testsuite flasg to + once they're pushed with the patch. Also, is there a way to verify this without the browser chrome testcases?
Some possible test sites: http://daringfireball.net/ - initial-scale=0.5, minimum-scale=0.45 http://sudoku.rectang.com/iphone/ - maximum-scale=1.0, user-scalable=0
