Improved mesh for "Palm Island Raft"

Mesh is now broken down into subsections and the texture-surface mapping should be simpler. The original island suffered from severe texture stretching, that should be fixed here.

List of texture sections:

Material 0 Leaves: Top of palm tree, flat texture, needs an opacity map to cut out shape of leaves, probably best if not blended. Please remember to replace the opacity map or it will not look good.

Material 1 Unterside of leaves: Top of palm tree viewed from below, flat texture, needs an opacity map to cut out shape of leaves, probably best not blended. If you use my material file it will share the same map as the top surface.

Material 2 Trunk: Opacity optional. Wrap-around texture.

Material 3 Top surface of raft "Sand": Flat texture

Material 4 Side of raft "Surf" : Wrap-around texture with repeats

Material 5 Base of raft: Flat texture

Templates here, but there's not a lot to it, the "flat" texture is just a big circle, and the wrap around texture is just like rolling paper around to make a cylinder.

List of OPTIONAL extra texture sections in "raftinside.xmf":

Material 6 Trunk inside surface

Material 7 Top of raft, inside

Material 8 Side of raft, inside

Material 9 Base of raft, inside

Note that for correct drawing of the inside surfaces the "raftinside.xmf" mesh must be first in the list followed by "raftoutside.xmf"
