Overview
Currently, NPAPI plugins have no way to know if the browser is running at a CSS zoom level other than 1x. We need an addition to the API that allows plugins to query the current browser CSS zoom level.
Specification
We'll need to add a NPNV variable:
NPNVCSSZoomFactor = 23
This value represents the current CSS zoom level of the browser. It will be sent to plugins via NPP_SetValue when the value changes. It can also be retrieved via NPN_GetValue. Since changing CSS zoom levels updates the window properties, this value can be re-queried during NPP_SetWindow or other window property update calls, to see if a zoom change has been made.
