279ef7880a - improved: geometric objects now use an adaptive drawing algorithm to represent curves (before e.g. ellipses were always separated into a fixed number of line-segments) 
- improved: constructors and access functions for several geometric objects (e.g. more constructors, additional functions to retrieve parameters in diferent forms, iterators for polygons, ...)
- new: all geometric objects can either be drawn as graphic element (i.e. lines are straight line, even on non-linear axes), or as mathematical curve (i.e. on non-linear axes, lines become the appropriate curve representing the linear function, connecting the given start/end-points). The only exceptions are ellipses (and the derived arcs,pies,chords), which are always drawn as mathematical curves
