So the bug description for Inkscape 0.92pre3 could be reduced to this?
«Using the feComponentTransfer filter primitive as a base for a threshold filter in discrete mode (for example with tableValues="0 1"), or linear mode (for example with slope="10" intercept="-5") lacks precision in the rendered output:
- at any zoom level the diagonal step in the fill from the filter doesn't go straight into the square's corner as it should.»
