Note on versioning.
Version consists of four numbers separated with dots. Each number has its own meaning and comparison
of any two versions of the software can immediatelly tell what kind of release we are looking at.

a.b.c.d

a - major change. Change of this field indicates major rewrite of the whole software or at least
change in the rendering engine.

b - feature change. Change in this field indicates this release is a feature release. When
any new feature is added this number is updated.

c - bugfix change. Change in this field indicates this release is a bugfix release. When
any bug is fixed this number is updated.

d - minor change. Change of this field indicates cosmetic changes to the software. It may be
better layout of the controlls or more detailed tooltips.

Change indicators are hierarchical. Change at the more significant position resets all the less
significant indicators to zero, and only then their values are incremented (if needed).
