Truncated Decimals in WKT Strings

When converting IGeometry to WKT with the AsText() method, decimal precision is lost as compared to other libraries (SqlGeometry, DotSpatial).

For example:
-108.45392758962691 becomes:

This is because internally your code is generating number strings for WKT via:

What it should be is:
stringBuilder.Append(num.ToString("G17", CultureInfo.InvariantCulture));

Actually, num.ToString("R", CultureInfo.InvariantCulture) seems to test better for compatibility with how other libraries handle rounding. I would like to request that.
