Gets most of the benefits of being a macro, but also gains type safety (which macros do not have).

* vm_screen.c
|
|
*
|
|
* Generally speaking the tests here are very incomplete; this is partly
|
|
* because a lot of the code in vm_screen depends on a third-party
|
|
* graphics library, but I think we can do a better job of decoupling
|
|
* some concepts (like screen areas) from the graphics library, such
|
|
* that we can make the code that uses those testable.
