This is not optimal since it involves a re-upload of the whole layer every frame. The way it's done for !CHROMIUM Mac, is that the ScrollbarTheme sets up the overhang area layer to just be a tiled pattern and the shadow layer to be some sort of magic path-based layer that are behind the content layers. We should do something similar. 562054 1 asvitkine 2012-02-22 09:38:53 -0800 Above should say "whenever the overhang is *visible*." 875741 2 schenney 2013-04-15 06:15:23 -0700 https://code.google.com/p/chromium/issues/detail?id=231285
