Build 3.5.0.10 of xlsgen has two fixes related to the behavior of vector shapes.

The first fix improves the anchoring of vector shapes when they are being read from a XLSX file. In the past, there could have been an offset of one cell horizontally and vertically.

The second fix is for the behavior of text rotation (both the angle and the vertical nature if applicable) so that it is consistent across reading and writing XLS and XLSX files.
