[Bug] Bitmaplayer flickering on zoom

[Fabioni]

Description

Using

  textureParameters: {
    minFilter: 'nearest',
    magFilter: 'nearest'
  },

in
Bitmaplayer results in flickering on zoom. See this video:

Flavors

• Script tag
• React
• Python/Jupyter notebook
• MapboxOverlay
• GoogleMapsOverlay
• CartoLayer
• ArcGIS

Expected Behavior

Clear shapes without flickering

Steps to Reproduce

/*
* https://deck.gl/docs/api-reference/layers/bitmap-layer
*/
const {DeckGL, BitmapLayer, COORDINATE_SYSTEM} = deck;

const layer = new BitmapLayer({
  id: 'BitmapLayer',
  bounds: [-123, 37, -122, 38],
  image: 'https://dummyimage.com/3200x3100/000/fff',
  textureParameters: {
    minFilter: 'nearest',
    magFilter: 'nearest'
  },

  opacity: 0.5,

});

new DeckGL({
  mapStyle: 'https://basemaps.cartocdn.com/gl/positron-gl-style/style.json',
  initialViewState: {
    longitude: -122.4,
    latitude: 37.74,
    zoom: 11,
    maxZoom: 20,
    pitch: 30,
    bearing: 0
  },
  controller: true,
  layers: [layer]
});

It also happens using this

const layer = new BitmapLayer({
  id: 'BitmapLayer',
  bounds: bounds: [-123, 37, -122, 38],
  image: 'https://raw.githubusercontent.com/visgl/deck.gl-data/master/website/sf-districts.png',
  opacity: 0.5,
    textureParameters: {
      minFilter: 'nearest',
      magFilter: 'nearest'
  },
  pickable: true,
});

but not this

const layer = new BitmapLayer({
  id: 'BitmapLayer',
  bounds: [-122.519, 37.7045, -122.355, 37.829],
  image: 'https://raw.githubusercontent.com/visgl/deck.gl-data/master/website/sf-districts.png',
  opacity: 0.5,
    textureParameters: {
      minFilter: 'nearest',
      magFilter: 'nearest'
  },
  pickable: true,
});

So maybe it only happens for larger bounds or has to do with the relationship between bounds and image resolution?

Does using 'linear' instead of 'nearest' improve it?

You want to avoid interpolation for some reason?

My feeling is that 'linear' just blurs the problem a bit, but it is still there.
