Hello Todd,

I have to disagree with you. It can also be a browser boolean option
like the existing "dither images" saying "refuse gradient
backgrounds". When a web server contains a great image with a too wide
colormap the browser cannot handle, it is the same thing, and such
images exist in the web. In fact, the web is full of this kind of

I understand that if the rendering engine knows the context, the
algorithm can be more (or less) efficient. But this is not IMO a good
reason why gradients should be left away. The problem you're
mentioning is related to the rendering medium, not to the styles.
