New issue 20474 by [email protected]: NPN_GetValue(NPNVnetscapeWindow) for  
windowless plugins
http://code.google.com/p/chromium/issues/detail?id=20474

http://codereview.chromium.org/180019 effectively disables
NPN_GetValue(NPNVnetscapeWindow) for windowless plugins. Flash uses that
value to do X calls to change/hide the cursor.

The problem is that the XID of the page window can change at arbitrary times
(e.g. when the tab is detached then reattached), so we need to be able to
track these changes, and let the PluginInstance know. This needs to be done
with synchronous calls to avoid races that would make the plugin issue X
calls with an invalid XID.
An alternative is to prevent that XID from changing, but I don't know if
it's possible.
