Changes

Accepted, ready for implementation. No NPAPI version number. = Problem Summary = We are proposing a NPAPI extension which would allow a plugin to render directly into 32-bit buffer in shared memory for performance reasons. = Specification = The plugin explicitly makes requests of the user agent whether the extension is supported (with NPN_GetValue and NPNVSupportsWindowlessLocal) and then enables the new rendering mode at runtime (with NPN_SetValue and NPPVpluginWindowlessLocalBool). In this way other plugins unaware of new extension will not be disrupted. When new rendering mode is enabled the Xdrawable field of a standardXGraphicsExpose event holds a pointer to the new NPImageExposestructure which among other things contains pointer to the sharedmemory buffer, its dimensions, translation and scale factors.
