Title: (Gene-trees) Long wedges are shortened and hatched

Hi again,

When the branches are too long, they are divided by 10, 100, etc, but not when they are collapsed. It causes pictures like: http://www.ensembl.org/Homo_sapiens/Gene/Compara_Tree?g=ENSG00000155363;r=1:113215763-113243368

The fix divides the length of the wedges by 10, 100, etc, following the same rule, and draws the wedges with hatchings:

Another example:

I didn't manage to add the symbols to the legend. I've found where to add entries, but I couldn't make triangles with the same pattern
