Detailed Description

Configuration object that triggers customizable behavior.

Warning: This class is strongly defined: that means that the class will fail if an undefined directive is retrieved or set.

Note: Many classes that could (although many times don't) use the configuration object make it a mandatory parameter. This is because a configuration object should always be forwarded, otherwise, you run the risk of missing a parameter and then being stumped when a configuration directive doesn't work.

$raw	Return a copy that has not been setup yet. Must be called before it's been setup, otherwise won't work.
$optimized	If true, this method may return null, to indicate that a cached version of the modified definition object is available and no further edits are necessary. Consider using maybeGetRawCSSDefinition, which is more explicitly named, instead.

Parameters

$type	Type of definition: HTML, CSS, etc
$raw	Whether or not definition should be returned raw
$optimized	Only has an effect when $raw is true. Whether or not to return null if the result is already present in the cache. This is off by default for backwards compatibility reasons, but you need to do things this way in order to ensure that caching is done properly. Check out enduser-customize.html for more details. We probably won't ever change this default, as much as the maybe semantics is the "right thing to do."
