[mkgmap-dev] Pending changes

Fri Feb 12 09:52:51 GMT 2021

Hi Ticker,

in fact 3200 - 3f1f strictly follow their given resolution value - other than e.g. 2a-2f, which only appear at kind of 24+, no matter what resolution is given.
Even if both ranges are styled to resolution 24: 2a-2f will always appear a bit later.
I suspect that´s what Gerd found to be confusing.
