Implement HiDPI support in Pepper dev interface
This patch requires WebKit patch https://bugs.webkit.org/show_bug.cgi?id=87874 (WebKit r121364)
Expose device_scale_factor and css_scale_factor to Pepper plugins via a dev
interface on View resource.
Allow Pepper plugins to create a 2D graphics context with a scale factor so the
plugins can render at device resolution rather than DIPs if they want.
