Absolute rotations and magnifications

[ajkeller34]

Rotations and magnifications of cell arrays and cell references are always flagged as absolute. This is unintentional and due to a misunderstanding of the GDS-II spec. It seems that some GDS-II viewers were ignoring these flags, but some were not, leading to inconsistent interpretations of the same pattern file, hence why the issue was not noticed until now. A fix is inbound.

• All files are now saved using relative angles and magnifications.
• When files are loaded, they are assumed to have relative angles and magnifications, although the GDS-II spec supports absolute angles and magnifications. Some patterns may not load properly.
• Eventually, absolute angle and magnification support could be added, but usually it is not what we want.
