 Technology Preview 2 :
-- When adding a texture layer (and maybe clouds), noise components cannot be used (they are always flat).
-- Texture preview is sometimes all black.
 - Render tab previews should not rerender when changing render options.
 - Compute shadows only once for all textures at a same location.
 - Add antialiasing option (pay attention to memory usage).
