Works around the issue where UITextView doesn't scroll to the new line until there's a character in there. Super horrible workaround.

Method to retrieve a list of downloadable fonts on iOS 7.
This method may block for a while (it can involve a network call) so don't call on main thread.
The return is a dictionary that maps font families to arrays of font names in that family.

A simple way to detect at runtime if we're running in UIKit legacy mode or the new "flat" variant. Written for our PDF iOS SDK (http://pspdfkit.com), where the precompiled binary needs to detect at runtime in what variant it's running. Want more stuff like that?
