/*
-* Explanation of the plasma fractal algorithm:
-*
-* A grid of points is created with the properties of a 'height-map'
-* This is done by making the corners of the grid have a random value.
-* The grid is then subdivided into one with twice the resolution.
-* The new points midway between two 'known' points can be calculated
-* by taking the average value of the 'known' ones and randomly adding
-* or subtracting an amount proportional to the distance between those
-* points. The final 'middle' points of the grid are then calculated
-* by averaging all four of the originally 'known' corner points. An
-* random amount is added or subtracted from this to get a value of the
-* height at that point. The scaling factor here is adjusted to the
-* slightly larger distance diagonally as compared to orthogonally.
-*
-* This is then repeated recursively to fill an entire 'height-map'
-* A rectangular map is done the same way, except there are different
-* scaling factors along the x and y directions.
-*
-* A hack to change the amount of correlation between points is done using
-* the grd variable. If the current step size is greater than grd then
-* the point will be random, otherwise it will be calculated by the
-* above algorithm. This makes a maximum distance at which two points on
-* the height map can affect each other.
-*
-* How fractal caves are made:
-*
-* When the map is complete, a cut-off value is used to create a floor.
-* Heights below this value are "floor", and heights above are "wall".
-* This also can be used to create lakes, by adding more height levels
-* representing shallow and deep water/ lava etc.
-*
-* The grd variable affects the width of passages.
-* The roug variable affects the roughness of those passages
-*
-* The tricky part is making sure the created floor is connected. This
-* is done by 'filling' from the inside and only keeping the 'filled'
-* floor. Walls bounding the 'filled' floor are also kept. Everything
-* else is converted to the normal _extra_.
