 - Add "hardness to light" and shadow control ("minimum lighting") to material.
 - Add logarithmic sliders for some float values.
 - Improve previews.

+   => Add user markers on OSD.
-- Add a zone editor dialog for localized textures.
+   => Add areas marking.
-- Add a terrain modifier dialog with zones.
+- Start a terrain editor (see mockup).
-- Use the curve editor in noise editor
+- Improve textures (current model is greatly incorrect).
+   => Separate models (basic texture and covering texture).
+   => Covering texture height should inpact terrain height.
+   => Add texture shadowing.
+- Use the curve editor in noise editor (option).
 - Add a noise filler (and maybe noise intervals ?).
 - Fix the distorted sun appearance.
 - Improve curve editor.
    => Add curve modes
    => Add logarithmic mode
    => Add zoom and scrolling
-- Fix "RGB parameters out of range" (and segfault) on preview while moving render params fast in render tab.
+- Fix "RGB parameters out of range" (and segfault) on some previews, caused by data changing during a chunk computation.
    => May need to change the updateData system.
    => Previews need to be paused while updating data.
 - Lock some previews together (eg: terrain height and colored preview).

 - Use bicubic interpolation for antialiasing.
 - Allow for larger renders/antialias (will need several two-pass chunks).
 - Add basic vegetation system ?
-- Texture shadowing and self-shadowing ?
 - Add a progress indicator on previews.
 - Multi threaded first pass.
 - Mark modified tabs and ask for losing modifications (idem for layers).
