I have a profile that I made for another purpose, and I noticed some stalls. Looking into the longest one, it seems like nsFrameLoader::GetWindowDimensions calls treeOwnerAsWin->GetPosition() followed immediately by treeOwnerAsWin->GetSize(), both of which end up calling nsWindow::GetScreenBounds that does not appear to be fast, at least on gtk running on X11.

I don't really know anything about this stuff, but is it possible that making a combined GetPositionAndSize() could save half of these calls?
