Parse, shift, and serialize an xl/drawings/drawing*.xml part.
Drawings are anchored to cells via <xdr:from> and <xdr:to> (or the
namespace-local forms) elements that contain <col>, <row>, <colOff>,
<rowOff> children. A structural row/column shift on the owning sheet
rewrites the row/col values inside each anchor.
The OOXML schema uses zero-based indices for drawing anchors while the shift primitive expects 1-based indices, so this module translates on the way in and out.
