translate in dc-path%
Adjusts all points within the path (including all sub-paths), shifting
then x to the right and y down. Future additions to the
path are not translated by this call.
A path is not connected to any particular dc<%> object, so
setting a dc<%> origin or scale does not affect path
operations. Instead, a dc<%>'s origin and scale apply at the
time that the path is drawn or used to set a region.
