Report the plugin position to windowed plugins as (0,0)

.  the NPAPI documentation says it should be reported relative to the parent HWND, which is the plugin's coordinates on the page.  This assumption breaks in Chrome because we have an intermediate HWND.  I've tested on a bunch of pages to see if this change causes regressions, if we find any in the future we can reconsider this.

BUG=6742
