Timo Tijhof c6cfe763bb Update OOJS UI to v0.1.0-pre (d047752ccc)
Also, as OOjs UI's StackPanelLayout was renamed to StackLayout, and the
showItem() function to setItem(), fix uses in VisualEditor.

/**
* Load the frame contents.
*
* Once the iframe's stylesheets are loaded, the `initialize` event will be emitted.
*
* Sounds simple right? Read on...
*
* When you create a dynamic iframe using open/write/close, the window.load event for the
* iframe is triggered when you call close, and there's no further load event to indicate that
* everything is actually loaded.
*
* In Chrome, stylesheets don't show up in document.styleSheets until they have loaded, so we could
* just poll that array and wait for it to have the right length. However, in Firefox, stylesheets
* are added to document.styleSheets immediately, and the only way you can determine whether they've
* loaded is to attempt to access .cssRules and wait for that to stop throwing an exception. But
* cross-domain stylesheets never allow .cssRules to be accessed even after they have loaded.
*
* The workaround is to change all `<link href="...">` tags to `<style>@import url(...)</style>` tags.
* Because `@import` is blocking, Chrome won't add the stylesheet to document.styleSheets until
* the `@import` has finished, and Firefox won't allow .cssRules to be accessed until the `@import`
* has finished. And because the contents of the `<style>` tag are from the same origin, accessing
* .cssRules is allowed.
*
* However, now that we control the styles we're injecting, we might as well do away with
* browser-specific polling hacks like document.styleSheets and .cssRules, and instead inject
* `<style>@import url(...); #foo { font-family: someValue; }</style>`, then create `<div id="foo">`
* and wait for its font-family to change to someValue. Because `@import` is blocking, the font-family
* rule is not applied until after the `@import` finishes.
*
* All this stylesheet injection and polling magic is in #transplantStyles.
