fractional heights in (0,1) are now multiplied by dimension ground
level, or surface height if surface relativity is enabled; surface
relativity is now inherited across distributions; still buggy
drop surface relative height support for cloud, veins and standard;
since those structures are generated (in general) before the chunks,
the height is not known.
<Substitute> now asks a block whether it can stay where placed before
placing it. This really only affects things like plants.
Determine "overworld-like" by looking for the default or ATG
generator. Also, rework BiomesOPlenty configuration to generate much
smaller veins, less frequently. Very much like diamonds now. Heights
are more realistic under the assumption that most gems are spawning in
pegmatites and/or metasomatic limestone.
<Substitute> now supports per x/z surface relativity, and searches
down past typical decorations until it hits a block of material rock,
sand, clay, dirt, grass, or ice.
Overhaul of Railcraft generation
No longer rely on fractional heights in BOP config.
Overhaul of Thaumcraft generation.
Fix the ore block for Forestry 2.3.0.6+.
