[cairo] Image loading and caching

[Enrico Weigelt, metux IT consult]

Hi folks,


in my widget toolkit (*1), I've got a lot of images to draw
(eg. window decorations and buttons, etc). For now, I'm loading
the images again for each button, which of course is a waste of
resources.

So, I'm looking for a proper way for caching. The quickest approach
would be just having some global pointers to the image surfaces and
loading them only once - just within the button widget.

OTOH, it might be worth implementing that in a generic way, maybe
even in cairo or some cairo-extension library.

What's your opponion on that ?
