+/*
+ TODO for better virtual list control support:
+
+ 1. less dumb line caching, we should cache at least all those visible
+ in the control itself and probably twice as many (we might also need to
+ cache the first one always for geometry calculations?)
+
+ +2. storing selections: we can't use an array to store the selected indices
+ like right now as selecting all in a control with 1000000 items is not
+ doable like this - instead, store selections as collection of individual
+ items and ranges
+
+ => wxSelectionStore
+
+ 3. we need to implement searching/sorting somehow
+
+ 4. the idea of storing the line index in the line itself is really stupid,
+ we shouldn't need it - but for this we have to get rid of all calles to
+ wxListLineData::GetFoo() and replace them with something like
+ if ( IsVirtual()
+ ... we have it ourselves ...
+ else
+ line->GetFoo();
+
+ => done
+
+ 5. attributes support: we need OnGetItemAttr() as well!
