How to resize citra window to exactly match 3DS screen dimensions

I’m trying to debug an application of mine and need to be able to locate the exact pixel positions and colors in Citra. However, it is hard (if not impossible) to resize the citra window so that the 3DS top screen is exactly 400x240 and the bottom screen exactly 320x240 pixel of size (on the host system, I mean). Is there a way how I can specify an exact emulator window inner size? I want that one pixel on the host system represents exactly one pixel on the 3DS (no linear scaling or anything). Is this possible?

Resize your window to the minimum size possible, it should match 3ds’s resolution.
