The world is ready. Visually. Mostly. More or less

Well, I wasn't doing nothing, you know. Actually it was quite a productive month. 

Changelog:

The world map is now fully filled with play zones. I haven't put much thought into the borders themselves, but I had a different goal in mind -- to test how the engine will behave with that many objects. And yes, drawing map chunks (every country/island is a separate polygon in my case) through draw_polygon() in _draw() was extremely slow, so I replaced this part of the graphics with many Polygon2D objects. Works MUCH better.

Building buildings and units is now "ready". I completely ignored the economic part of the process, for I am concerned mostly with graphics now, but now it is possible to build and move units on the scale of a separate zone (active/reserve units)

A huge number of smaller and boring things are improved too.

Overall, the progress is so big that I decided to start counting the version number. Welcome reWinWar 0.0.1! But no, the game is nowhere near to be playable yet.
