The type is specific about printing, so give it a name in line with
QPageLayout and QPageSize.
As per API review comment, it's not clear why this type should not be a
regular, copyable and movable value type. It stores a list of intervals.
Give it value-type semantics, as an implicitly shared class.
Convert the parse method into a static factory function.
Add a Range type and use it instead of the semantic-free QPair.
Move QPrinter getter into QPagedPainteDevice, make it return a copy
rather than a pointer, and add a setter.
Extend test case to cover all members and more merge cases. Fix bugs
found that way.
