Quick: Add experimental.viewport.devicePixelRatio
This specifies a devicePixelRatio to be used by web content instead of
the QScreen::devicePixelRatio(). This is necessary on non-iOS mobile
devices to remain compatible with the mobile web which assumes
devicePixelRatio is computed as the ratio of actual dpi to 160 dpi.
Non-iOS mobile platforms may use different criteria to determine the
QScreen::devicePixelRatio(), depending on the history of the platform,
or simply leave it at 1.0.
For QNX, this setting gets a reasonable default value so developers
don't have to regularly use this experimental API.
These changes were inspired by the Android Chromium port which uses a
GetDpiScale() to accomplish the same in
content/browser/android/content_view_core_impl.cc.
