Description Yusuke Suzuki 2016-05-18 10:43:53 PDT 
In Cairo environment, device scale factor is transparently handled by HW side using cairo_surface_set_device_scale.
ImageBuffer ignores resolution factor now. So we Filter and FilterEffect should not consider that ImageBuffer's size is scaled.

This leads crash in kangax's ES6 compat table page in HiDPI PC.
