We are hoping to make 3 major improvements to the Mac OS X plugin architecture in Gecko 1.9:
* [https://bugzilla.mozilla.org/show_bug.cgi?id=344425 344425] - support NP_GetEntryPoints as a way to get plugin function pointers instead of calling "main()"* [https://bugzilla.mozilla.org/show_bug.cgi?id=336060 336060 ] - use a slower idleEvent timer for plugins that are not in a foreground tab on the key window
* Support 64-bit Mac OS X NSAPI, as proposed on the plugin-futures mailing list. Significant changes include the option to render via CoreGraphics (QuickDraw will no longer be the only option) and updated native event structures.
