Reduce artefacts significantly by binning the "LO_TWIPS_TO_MLO_RIP_RATIO"
Reduce artefacts significantly by binning the "LO_TWIPS_TO_MLO_RIP_RATIO"

Change it from 10 to 1. This makes occasional rendering artefacts at
tile boundaries much less visible. Unless there is opposition to this
change, I will separately commit a change that simplifies the
code. Now that LO_TWIPS_TO_MLO_RIP_RATIO equals one, no point in
having it at all, and dividing or multiplying by it.
