[Dojo-interest] widgets, template and css

[Peter Higgins]

So if two widgets require the same "base css" you get multiple <link /> 
elements?

Also, the build system concatenates css files into one for fast loading 
in production ... How would a "css layer" alert code that a 
dojo.requireCss() has already been resolved within? (dojo._hasResource 
is what the build uses for js, but we can't execute anything in css) ...

We've looked down this path before, but as I said, never came up with a 
solution that "works"
