The Deep Zoom implementation in OpenSlide Python never upsamples. For
example, CMU-1.svs has these downsample values:
When OpenSlide Python is rendering the Deep Zoom level with downsample
16, it will read pixels from slide level 1 and scale them. That is
probably more cautious than necessary, and will have a negative impact
on performance. However, I don't have a recommendation for how much
upsampling to allow. Does anyone else have experience with this?
