Better way to handle "virtual" resolutions

[percyqaz]

Interlude is designed around a landscape 1080p screen

UI stuff is designed to naturally expand when the window is larger

For SMALLER resolutions, the game/screen/ui/everything is scaled down - The game draws things in terms of "virtual" pixel -- This ensures a virtual 1080p box (1920x1080) of virtual pixels exists to fit all of the UI

This image illustrates this - The red box represents the familiar proportions of the game - The rest of the space is used by the UI naturally growing to fill it
In portrait mode, this causes scroll speed to seem lower/column width to be thinner because the top section of the screen acts in proportion with normal, and everything below is would not normally be seen.

---

This is not desirable:

• Portrait play (for whatever reason you might do it) is difficult to adjust to because of the change in proportions rather than the expected "trim off the sides" effect
• Playing on larger screens breaks the UI a bit AND requires adjustment when it should just have the same proportions as 1080p

So I suppose we should just scale everything so that the height of the screen acts like 1080p

Portrait mode gameplay cannot be properly supported due to crushing the UI in this case, which is why I didn't do it like this originally

Resolution stuff:

• Detect when resolution changes to prevent certain issues like the logo hanging when you widen the screen

• Scale always to a height of 1080p
  Game is not suited for 4:3 (or thinner for portrait)! what do about this

• Ability to set up custom resolutions easily from settings menu
