SetWindowSize() and Layout() sizes not matching at fractional display scale factors about ebiten HOT 2 OPEN

I wasn't sure that having SetWindowSize() and Layout() sizes match would even be possible, but after more detailed testing, I think it should be possible, this looks more like an internal scaling calculation mistake than an OS limitation.

Do you have an idea how to fix this?

For context, having this work correctly is useful for setting perfect windowed sizes on pixel art games.

I'm not sure we can render something in a pixel-perfect way with 125% mode.

No, I'd have to go through the code to figure out if some floor or ceiling is being applied too early at some point or something like that.

Ignoring macOS and retina displays and all those apple things, yes, the device scaling is indifferent for rendering pixel perfect art. Notice that I'm not saying "render pixel art perfectly at an arbitrary scale", but "being able to set a window size compatible with our pixel art" (perfect multiple). This only depends on SetWindowSize() setting the requested size perfectly, which is what's not happening here.
