Forthcoming patch moves the Screen object out of the JS bindings code and autogenerates a wrapper instead.
Created attachment 15081 [details] patch
One change from the old code that this patch makes is that the properties of the Screen object used to be DontEnum|ReadOnly and now are DontDelete|ReadOnly. I found no documentation or reason that the screen properties should be non-enumeratable and deletable so I changed them to be just like all the the other js objects we generate. This change is visible in the changed results of the regression tests.
Comment on attachment 15081 [details] patch r=me Will the other platforms' projects need to change to accommodate the new file paths? Maybe you should send email to webkit-dev.
