   zoom, 
   resolution,

   screenHeight
): GridPlacement;

Defined in: src/core/gridPlacement.ts:20

The pixel grid's arithmetic (PixelGrid). originX/Y is where the camera put the world's origin on screen (the scroll, plus any shake), zoom screen pixels a world pixel, resolution backing pixels a screen pixel. The texture starts on the whole world pixel at the screen's corner and is moved by what is left over, rounded to a backing pixel, so a world pixel never lands between two.
