Demonstrate alpha mask, render order change & occlusion disable with a new example material in the SceneLoadExample demo scene. Porting note added related to missing techniques.

@@ -1040,7 +1040,8 @@ From 1.6 to master:
 - SoundSource autoremove boolean was replaced with AutoRemoveMode enum, which allows removing either the component or owner node. Also used by ParticleEmitter.
 - Getting camera projection matrix has changed. Use GetProjection() to get the API-independent matrix, and GetGPUProjection() to get the matrix converted to be usable as a shader parameter. On D3D these are the same.
 - Alpha masking hint has been removed from Technique & Pass, due to materials also now being able to define additional shader compilation defines. You can use Material::SetRenderOrder() instead to ensure that partially opaque geometry will be drawn after fully opaque for GPU depth buffer optimization.
-  Due to this change you must also manually define that a material should not take part in occlusion rendering, see Material::SetOcclusion().
+  Due to this change you must also manually define that a material should not take part in occlusion rendering, see Material::SetOcclusion(). 
+- Techniques that existed just for shader defines like ALPHAMASK and PACKEDNORMAL have been removed. Replace by using techniques without those defines (e.g. DiffNormal instead of DiffNormalPacked), and adding the necessary defines to your materials instead.
