> At the moment, only the text dialog is the same between Histogram2 and Profile. The options dialog in Profile could be made to work like that in Histogram2, but not the other way around. The raster input dialogs are quite different and probably need to remain so.

> Histogram2 can have a variable number of maps to histogram (from one theoretically up to the maximum number supported by i.group) and doesn't need  transect drawing code or code for segment markers. Hence, the dictionaries for tracking parameters like line color and width are a bit simpler in Histogram2 (one less level so that the raster name rather than an index number main key) making it easier to keep track of a potentially larger number of raster maps.

everything leads to the suggestion that ProfileFrame and
histogram2.HistFrame should be inherited from the common super-class,
probably same for settings dialogs except of RasterSelect.
