Lookup table for color indices in static and dynamic landscapes. Colors 0-127 are matched to a material-texture-reference.
Colors 128-255 are matched to the same list of references only these are marked 'underground'.
The engine will draw materials with a higher index above those with a lower index so that, e.g. using the standard table,
rough chunks of earth will overlap water which has a smooth border. Mineral resources have an even higher index so that their
rough border overlaps the earth and not the other way around. This is also the reason why there might be differing numbers
of total pixels of a given material drawn than you might expect just from calculating the square sizes of the unzoomed map
materials.
If a custom map fails with the message 'texture n undefined' you should define the specified texture in the TexMap. You should
always use a paint program capable of editing indexed color palettes without modifying the palette (MS Paint is not suited
for this).
If TexMap.txt contains OverloadMaterials
OverloadTextures at the beginning materials / textures from the default Material.c4g are loaded before the custom definitions, which may also
override the default definitions.
