Original behavior. Best quality was rendered at 1000 pix, artifacts observed when rendering at 500 or 2000.

I tested on another dataset, so far only 4 tested (kitchen, truck, playroom, and desolation). Where 3 of them (truck, playroom, and desolation) I see a little bit improvement.

Kitchen dataset with splatfacto-v101:

Kitchen dataset with --pipeline.model.rasterize-mode 'standard':

playroom dataset:
Left = Using --pipeline.model.rasterize-mode 'standard'
Right = using Splatfacto v1.0.1, so it don't use this rasterization.

kitchen dataset: it was a frame from video which come from ns-render result. So, it does not screenshot the 3DGS Web viewer.

playroom dataset: it was the screenshot from mkellogg 3D WebGL Gaussian Splat.
