* depends on the normal case being that style rules specify relatively
* few properties and even that elements generally have relatively few
* properties specified. This allows sharing in the following ways:
* 1. [reset structs] When a style data struct will contain the same
* computed value for any elements that match the same set of rules
* (common for reset structs), it can be stored on the nsRuleNode
* instead of on the nsStyleContext.
* 2. [reset structs] When (1) occurs, and an nsRuleNode doesn't have
* any rules that change the values in the struct, the nsRuleNode
* can share that struct with its parent nsRuleNode.
* 3. [inherited structs] When an element doesn't match any rules that
* change the value of a property, the nsStyleContext can use the
* same nsStyle* struct as its parent nsStyleContext.
* 1. [mainly reset structs] When a style data struct will contain the

* 2. [only? reset structs] When (1) occurs, and an nsRuleNode doesn't

* nsRuleNode can share that struct with its parent nsRuleNode.
* 3. [mainly inherited structs] When an element doesn't match any

* when all the values specified are 'inherit'), the nsStyleContext

* Since the data represented by an nsIStyleRule are immutable, the data
