make the render process DPI-aware
On Windows, system calls that retrieve screen properties (like GetSystemMetrics to get the size of a scroll bar button) are dependent on the DPI awareness setting of the calling process. The render process must use the same DPI awareness setting as the browser process. Retrieve the DPI awareness of the parent process in the render process and set it accordingly.
