+ REGRESSION (r181910): WKWebView incorrectly scales snapshot
+ https://bugs.webkit.org/show_bug.cgi?id=145076
+
+ Reviewed by Tim Horton.
+
+ We added a fast path to snapshotting using IOSurfaces with
+ http://trac.webkit.org/changeset/181910 which incorrectly determined
+ scale and transform and resulted in bad snapshots in some situations.
+
+ * UIProcess/API/Cocoa/WKWebView.mm:
+ (-[WKWebView _snapshotRect:intoImageOfWidth:completionHandler:]):
+ When snapshotting an IOSurface we need to compute our scale based off of
+ the rect in the WKWebView coordinates, we also failed to account for
+ non-zero origins in the snapshot rect. Remove an unused varible while
+ we're here.
