DARKNET: Refactor/adjust getPixelPosition (#2501)

Browse Source 
This simplifies the logic. It also adjusts the position of special
servers slightly; in particular, they are horizontally centered
(appearing in-between the adjacent row, and not merely staggered).

The split into two functions is in preparation for perf improvements
that require calculating this without access to the server.
