-// is never called with NPNWindoTypeDrawable and NPWindow set to NULL.
-// Doing so allows removing NPP_SetWindow call during painting a windowless
-// plugin, which otherwise could trigger layout change while painting by
-// invoking NPN_Evaluate. Which would cause bad, bad crashes. Bad crashes.
-// TODO(dglazkov): If this approach doesn't produce regressions, move class to
-// webplugin_delegate_impl.h and implement for other platforms.
