By the way, I don't know if Il-2 can pull this off, but the rivers flowingthrough Sofia are actually very small.

Rivers are a difficult thing to pull off well. You need to make them 3 pixels wide on the large My_mapc or else they end up as pools of water dotted along a landscape. But at 3 pixels wide, they flow as a continuous stream at least, but are a bit on the wide side ... but the when they end, it is not really possible to let them taper off ... they end in a half circle that looks like an inland bay almost ...

But I've not found any solution yet - aside from not blurring rivers and coastline, but that looks like a Cubist rendition of a landscape - all geometrical figures and shapes ... even worse.
