- Automatically create CSS sprites?
That would be neat, but perhaps a bit tricky.
Just trying to think how it'd work.
Given a CSS selector, and an image, should be able to construct
a
stylesheet which sets the background property of the css
rules and an
single image.
(#toolbar-copy, toolbar-copy.png) (#toolbar-copy:hover, toolbar-copy-hover.png)
And the generated stylesheet would get concatenated with other stylesheets.
Again, I like sprites allot! But in reality, they are an
optimization
technique that needs careful attention and can cause
problems if done
improperly.
Providing CSS sprite support would be (I guess) just a service for
modules/extensions to use, just as a part of the proposed client resource manager(?). So the mediawiki or an extension can put in a
request for a some stylesheet or javascript be linked to, it could
also request for images possibly via CSS sprites.
So don't see how it should cause a problem.

So you are saying that you believe a generic set of sprite-generation utilities are going to be able to completely overcome the issues I identified and be a better use of time (to design, develop and use) than just creating and using sprites manually?

I wouldn't say there a issues with CSS sprites, but there are limitations which you have to be aware of before deciding on using them, and therefore do not need overcoming.
In the context of providing toolbar imagery for UIs like a WYSIWYG editor, or for playing video, audio, or for simple image editing, they can remove a lot of round triping.
