Hi!
Quite a while ago, I've experimented with the map display to show/hide
features only at a specific zoomlevel of the JOSM map display.
At that time, the display was so slow that removing specific features
from the map was an idea to speed up the map display. Since then I've
spend quite some effort to increase the map speed, which made the whole
scale tag thing obsolete IMHO.
The two values of scale_max / scale_min that are currently spamming
elemstyles.xml (the mappaint style file) are actually unused AFAIK.
Are there any objections against removing the remaining traces of these
experiments?
No objections. Maybe we can switch the default value of
mappaint.zoomLevelDisplay from false to true afterwards. This way
authors of external style sets can create fancy scale dependent styles
and don't need to bother their users with advanced preferences
configuration.
Btw., I have mostly completed mapcss support (which offers zoom
dependent markup, as well), but it will take some time to integrate into
JOSM. A lot of existing code needs to be adapted and I don't want to
break too much...
E.g. the z-index property does not work well with the way multipolygons
are drawn in the PaintVisitor.
