+ Update pages' style and content scale when the window's backing scale factor changes
+
+ Unfortunately, I couldn't think of a way to test this in an automated fashion.
+
+ Fixes <http://webkit.org/b/66229> <rdar://problem/9906269> WebKit doesn't react to device

+ Reviewed by Simon Fraser.
+
+ * WebCore.exp.in: Export Frame::deviceOrScaleFactorChanged.
+
+ * page/Frame.cpp:
+ (WebCore::Frame::deviceScaleFactorChanged):
+ * page/Frame.h:
+ Added this new function. We recalc style so that, e.g., device-scale-factor-dependent media
+ queries will be reevaluated, and we tell compositing layers about the new scale factor so
+ they can rerender at the new resolution.
