 Textures for POV-Trees      
Uses javascript to show images in higher resolutions

In a POV-Tree data file of a blob tree ('Save as ...')
there are declared the colors of the trunc (incl. branches and twigs).
Also the colors of the leafs are declared in this file.
We can change these values by opening this include file in POV-Tree,
change the values in the according POV-Tree section and then save the file again.

Another simple method is to overwrite the according values by new declarations.
   For details about the function of all the parameters for blob trees by TOMTREE.inc see the listing in 'tomtree.txt'.

Changing foliage colors:
The basic blob tree as declared by
"povtree_001.inc" with springtime colors:
