It is my understanding that automatically clearing the page to the background color is intentionally left out of the extcairo device intentionally so that the provided context is preserved. This way a user can provide, for example, an image they want to plot over and it will be preserved. I use this feature of the driver quite often, so I would prefer that the extcairo functionality remain as-is, at least in the default case. Hez -- Hezekiah M.
