performance: Orthographic Slice View poor performance with large images
The Orthographic Slice View slows to a crawl for images around 512x512x512.
Steps to reproduce
- Start ParaView 5.6.0
- Add Wavelet source, extent set to [0, 511, 0, 511, 0, 511]
- Convert the default Render View to Orthographic Slice View.
- Make the Wavelet source visible.
ParaView takes a very long time to show the slice views.
In addition, attempting to change slices with the controls on the edges of the view cause ParaView to stall.
