Feature requrest: Simplify origin to {0,0} wherever possible

[CSchoel]

The parameter origin is only needed if it is used together with a rotation, otherwise we can set origin to {0,0} and add the old origin to all points in extent and points.

This would avoid awkward definitions such as

Line(
  origin= {-100,2145.04},
  points= {{100.05, -2159.81}, {100.05, -2135.89}},
  thickness= 0.5
)
