-/*
- * The algorithm used for lineing up the icons could be called
- * "beating flat the icon field". Imagine the icon field to be some height
- * field on a regular grid, with the height being the number of icons in
- * each grid element. Now imagine slamming on the field with a shovel or
- * some other flat surface. The high peaks will be flattened and spread out
- * over their adjacent areas. This is basically what the algorithm tries to
- * simulate.
- *
- * First, the icons are binned to a grid of the desired size. If all bins
- * are containing at most one icon, we're done, of course. We just have to
- * move all icons to the center of each grid element.
- * For each bin which has more than one icon in it, we calculate 4
- * "friction coefficients", one for each cardinal direction. The friction
- * coefficient of a direction is the number of icons adjacent in that
- * direction. The idea is that this number is somewhat a measure in which
- * direction the icons should flow: icons flow in the direction of lowest
- * friction coefficient. We move a maximum of one icon per bin and loop over
- * all bins. This procedure is repeated some maximum number of times or until
- * no icons are moved anymore.
- *
- * I don't know if this algorithm is good or bad, I don't even know if it will
- * work all the time. It seems a correct thing to do, however, and it seems to
- * work particularly well. In any case, the number of runs is limited so there
- * can be no races.
