+20100513 Accuracy problems detected in TT.points.in.classes() for texture data
+ located right on the boundary of the triangle (or some texture classes),
+ with some digits after the decimal: due to non-exact trigonometric
+ calculations (around 1E-15), these points may not be classified
+ as on the border, or even belonging to the texture class. These
+ accuracy problems can be partially fixed by a new parameter of
+ TT.points.in.classes(), 'texture2xy' that can be set to FALSE in
+ order to get more accurate classifications. Other accuracy problems
+ still remains, but this time in the underlying point.in.polygon()
+ function. There is no easy fix to this:
+ <https://stat.ethz.ch/pipermail/r-help/2010-May/239035.html>
+ No fix are planned in the close future to fix this error.
+ Thanks to Wei Shangguan (see below) for pointing this 'bug'.
+
+20100513 Added the ISSS (not the 'Australian ISSS') texture triangle to the
+ list of pre-defined texture triangles. Many thanks to Wei Shangguan,
+ PhD student at the School of geography of Beijing normal university
+ for providing the code of the triangle.

20100416 Added the Canadian texture triangle to the list of pre-defined
texture triangles.
