Now, all this flexibility does come at a price - because the smallest graphical unit is a pixel, and most provinces are going to be only a few dozen pixels square at most, there is going to be a degree of "blockiness" to the map that simply can not be avoided. Even with the HoI3 map being 3x the size of the EU3 map, the simple reality is that the overall size of the map means that a pixel in size will be more than a few dozen square miles, making it rather more difficult to represent a potential perfectly "smooth" border. It would only be possible to have "smooth" borders if the base map were to be something say 9x the size of the EU3 map (something say the size of the Clio map project I'm working on for Victoria, which has dimensions of approx 30Kx12K pixels), so that individual pixels represent a much smaller area of land and even the smallest provinces would be several hundred square pixels square in size. And a map that size, with all of the functionalities of the EU3 map, would likely require everyone to have super-power graphics cards that few today have. Most computers, facing a map as large as Clio based on EU3's map structure, would probably seize up.
