With non-16:9 screen aspect ratios, the lights are no longer properly rendering

[Kermalis]

If you match the GRID_SIZE_X and GRID_SIZE_Y in the light cull shader and the RenderManager to the aspect ratio of the screen, then they work fine. But those are constants, so a generic handling of this must be made for the target resolution

For example, by default, the screen is 1920x1080, and the grid size X and Y are 16 and 9. This matches.
If you will make the screen 640x640, then you have to update the shader and render manager to change Y to also be 16. Then it also matches the aspect ratio (1:1) and works fine for that screen size

The culprit is Screen2View. The x aspect ratio is stored but the Y is not. I'll look into it and see if that can be changed without changing the grid size
