added missing preprocessor symbol (_VARIADIC_MAX#6) for release
Merge branch 'master' of github.com:Wumpf/mstbasedheightmapgen
fixed precompiled header setting in release mode
basic noise value works now with new ui/processing system
* added CmdBlendOverwrite
* important bugfixes for GeneratorPipeline
* untangled some confusion with height:
** input for terrain preview is defined as normalized (so far nothing new)
** only one scaling factor, no terrain offsetting in min/max (-> min/max during processing won't play any role for rendering) -> rendering relies only on visual height scale
* added default values for sliders
** currenlty only used in ValueNoise.cs
