General Qt implementation notes:
* it seems like Qt doesn't offer a way to constrain the aspect ratio of a view by constraining
the size of the window (i.e. you can use a custom layout to constrain a view, but that won't
affect the window, so isn't useful for this project). Therefore the emulation window resizes freely.

// Qt is the worst.
//
// Assume your keyboard has a key labelled both . and >, as they do on US and UK keyboards. Call it the dot key.
// Perform the following:
// 1. press dot key;
// 2. press shift key;
// 3. release dot key;
// 4. release shift key.
//
// Per empirical testing, and key repeat aside, on both macOS and Ubuntu 19.04 that sequence will result in
// _three_ keypress events, but only _two_ key release events. You'll get presses for Qt::Key_Period, Qt::Key_Greater
// and Qt::Key_Shift. You'll get releases only for Qt::Key_Greater and Qt::Key_Shift.
//
// How can you detect at runtime that Key_Greater and Key_Period are the same physical key?
//
// You can't. On Ubuntu they have the same values for QKeyEvent::nativeScanCode(), which are unique to the key,
// but they have different ::nativeVirtualKey()s.
//
// On macOS they have the same ::nativeScanCode() only because on macOS [almost] all keys have the same
// ::nativeScanCode(). So that's not usable. They have the same ::nativeVirtualKey()s, but since that isn't true
// on Ubuntu, that's also not usable.
//
// So how can you track the physical keys on a keyboard via Qt?
//
// You can't. Qt is the worst. SDL doesn't have this problem, including in X11, but I'm not sure I want the extra
// dependency. I may need to reassess.
