+| This node can render quit large terrain consisting of tiles by storing data  |
+| of individual tiles in array and rendering only part of terrain around       |
+| defined position and in defined size. This can be position of another scene  |
+| node defined by user and terrain node can be set to render around it         |
+| automaticaly.                                                                |
+| It is done by creating mesh of given size which then glide over invisible    |
+| data skelet like a peace of soft cloth, updating its atributes from data     |
+| arrays each time it shifts to a new position.                                |

+| Diferent atributes of individual tiles can be adjusted, most of them on run  |
+| time. Namely texture coordinates, position of tile vertices, normals and     |
+| color.                                                                       |

+| Firsth texture is standard texture which gives detail to terrain close by    |
+| and can by assigned to individual tiles by setting their UV coordinates.     |
+| User have complete freedom as howe to apply this texture to tiles. Texture   |
+| can for example consist of seweral subtextures and each can be set to        |
+| diferent tiles using UV coordinates.                                         |

+| Second texture is created by terrain node internaly and is used to render    |
+| color of individual tiles. This adds some variability to terrain at distance.|
+| Both textures are blended together using EMT_DETAIL_MAP material type.       |
+|                                                                              |
+| Normaly textures should be set in oposite order but there are some bugs with |
+| updating texture under OpenGL so until it gets solved I have to stick with   |
+| detailmap applyed as firsth texture layer. Not perfect but working.          |
