Castle Game Engine: Float-based images (e.g. for precise terrains) full support: 4 float-based image classes (passed to GPU and shaders), loading 16-bit PNG, loading float-based KTX, loading 16/32-bit TIFFs, Castle Image Viewer improvements

We added to Castle Game Engine capability to read 16-bit and higher precision image formats. This is useful for precise terrains (where you want to store heightmaps with more precision than 8-bit) or any other data that you may want to process (in shaders or using Pascal code) where 0..255 range (8-bit integer, i.e. byte) …
