/*
* 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.
