/**
* Construction context for style structs.
*
* Certain Gecko style structs have historically taken an nsPresContext
* argument in their constructor, which is used to compute various things. This
* makes Gecko style structs document-specific (which Servo style structs are
* not), and means that the initial values for style-structs cannot be shared
* across the entire runtime (as is the case in Servo).
*
* We'd like to remove this constraint so that Gecko can get the benefits of the
* Servo model, and so that Gecko aligns better with the Servo style system when
* using it. Unfortunately, this may require a fair amount of work, especially
* related to text zoom.
*
* So as an intermediate step, we define a reduced API set of "things that are
* needed when constructing style structs". This just wraps and forwards to an
* nsPresContext in the Gecko case, and returns some default not-always-correct
* values in the Servo case. We can then focus on reducing this API surface to
* zero, at which point this can be removed.
*
* We don't put the type in namespace mozilla, since we expect it to be
* temporary, and the namespacing would clutter up nsStyleStruct.h.
* TODO: marked for removal.
