Add a channel for translucency in images

[GoogleCodeExporter]

A really bold suggestion, but seeing that GIF had transparency 21 years ago and 
WebP is "something new", I think it's not a bad thing to have share my thoughts 
about it.

I'd like to propose to include a channel for translucency.

What I mean by this is to gain the ability to render the given color on the 
surface diffusely rather than using an opacity, making the underlying surface 
unclear and/or blurry.

To my knowledge this is not yet possible for web-based image formats, and I 
believe it's something which certainly could add value to the web. Right now an 
effect like this could be simulated using, for example, the HTML5 <canvas> 
element.

Transparency and translucency are not the same, it's not a dupe.
