// Properties to process
// Extend this object in order to add support for more properties in the optimizer.
//
// Each key in this object represents a CSS property and should be an object.
// Such an object contains properties that describe how the represented CSS property should be handled.
// Possible options:
//
// * components: array (Only specify for shorthand properties.)
// Contains the names of the granular properties this shorthand compacts.
//
// * canOverride: function
// Returns whether two tokens of this property can be merged with each other.
// This property has no meaning for shorthands.
//
// * defaultValue: string
// Specifies the default value of the property according to the CSS standard.
// For shorthand, this is used when every component is set to its default value, therefore it should be the shortest possible default value of all the components.
//
// * shortestValue: string
// Specifies the shortest possible value the property can possibly have.
// (Falls back to defaultValue if unspecified.)
//
// * breakUp: function (Only specify for shorthand properties.)
// Breaks the shorthand up to its components.
//
// * restore: function (Only specify for shorthand properties.)
// Puts the shorthand together from its components.
