[Maintenance] Declare distinct types for screen, VRAM, and TRAM coordinates Whew, time to look at every `int` variable we ever declared! The best moment to do this would have been a year ago, but well, better late than never. No need to communicate that in comments anymore. These shouldn't be used for widths, heights, or sprite-space coordinates. Maybe we'll cover that another time, this commit is already large enough. Part of P0111, funded by [Anonymous] and Blue Bolt.

[Maintenance] Declare distinct types for pixel and VRAM sizes Oh wait, we also need one of those for an upcoming structure! Part of P0111, funded by [Anonymous] and Blue Bolt.
