QRect: plaster API with Q_DECL_NOTHROW
This is mostly straight-forward, but some things are worth noting:
1. Yes, this is necessary. The noexcept operator looks for noexcept tagging,
not at the contents of the function to determine whether to return true.
The more conditionally-noexcept functions are used, the more important it
becomes that low-level classes are correctly marked noexcept. In that, it
is like constexpr.
2. In accordance with the rules governing noexcept specifications for the
standard library itself, the get*()-family of functions are not marked
as noexcept, since they have preconditions and thus a narrow contract.
Narrow-contract functions should not be noexcept. All other functions
have wide contracts (ie. no preconditions).
