comparison layer/Layer.cpp @ 1537:4f8c72adbf43

Clarify naming of some view-related methods. Rename LayerGeometryProvider::getValueExtents to getVisibleExtentsForUnit, and View::getTextLabelHeight to getTextLabelYCoord. Add View::getVisibleExtentsForAnyUnit to be used to determine which unit to adopt in a new e.g. box layer.

 
     if (!getValueExtents(min_, max_, logarithmic_, unit)) {
         return false;
     }
 
-    if (!v->getValueExtents(unit, min, max, logarithmic)) {
+    if (!v->getVisibleExtentsForUnit(unit, min, max, logarithmic)) {
         return false;
     }
 
     if (min != min_ ||
         max != max_ ||
