Pressure I: Under Pressure

The pressure systems of Earth are deeply complex, as as the winds they generate.

All I need to know is that wind flows from high points to low points and is affected by the Coriolis Force.

Easy to say, easier to implement. I used the guide here to set my initial pressure map, then used Inkscape to transform that into SVG paths. I was at a loss at first when thinking about how to take a gradient map and turn it into a wind flow field, but then I realized that I could just discretize the paths (black to white for low to high) and "walk" along the edge of each one. That would give me a rough outline of vectors for my winds. Its rough, it's not the 20-mile level of detail I'd want, but it's computationally cheap (not a simple thing (on my middle tier machine) if I were to use 200k objects), and it gets me what I want.

Both the "summer" and "winter" maps are considered, as the pressure is distributed differently during each macroseason. For most of the climate-related stuff, I'll have two maps, one for each macroseason, because of the way that the climate classifications are usually defined.
