// So. Fun story. From https://github.com/cefsharp/CefSharp/issues/738#issuecomment-91099199, we need to set the zoom level
// in the FrameLoadStart event. However, the IWpfWebBrowser's ZoomLevel is a DependencyProperty, and it wraps
// the SetZoomLevel method on the unmanaged browser (which is exposed directly by ChromiumWebBrowser, but not by IWpfWebBrowser).
// Now, FrameLoadState and FrameLoadEnd are called on a background thread, and since ZoomLevel is a DP, it can only be changed
// from the UI thread (it's "helpful" and does a dispatcher check for us). But, if we dispatch back to the UI thread to call
// ZoomLevel = xxx, then CEF seems to hit threading issues, and can sometimes render things entirely badly (massive icons, no
// localization, bad spacing, no JavaScript at all, etc).
// So, in this case, we need to call SetZoomLevel directly, as we can do that from the thread on which FrameLoadStart is called,
// and everything's happy.
// However, this means that the DP value isn't updated... Which means we can't use the DP at all. We have to call SetZoomLevel
// *everywhere*, and that means keeping a local field zoomLevel to track the current zoom level. Such is life
