// What we want is the mouse position to stay the same relative to the zoomable object (it's a map in this example)
// To do that we solve the equation "oldMouseRelativePos = newMouseRelativePos" to find the value of newMapOffset.
// We know the values of oldZoom, newZoom, oldMapOffset and mousePos
//
// It is assumed that canvas->screen (something you would use in OpenGL, for example) transform is "(p - offset) / zoom",
// meaning screen->canvas (something you would use in Canvas2D) transform is "p / zoom - offset".
// mousePos is assumed to be in some kind of screen coordinates
// mapZoom is assumed to be zooming relative to the top left corner of the map
//
// "map relative mouse position" is:
