Mark Lines have Bad Anchors

[johannes-wolf]

See: #246. The anchors seem to get moved with the mark, which is wrong.

Not sure whether this is related, but if you increase the stroke to, say e.g. 2pt, it will also be placed incorrectly.

Can you post the source used to generate the image? To get the start/end of a line use the "start" and "end" anchors, as "left", "right", ... default to the bounding box, which does not take the stroke into account and therefore is a bit smaller than expected!

Sure, this is where it happens:

#import "@preview/cetz:0.1.2": canvas, draw, tree

#canvas(length: 1cm, {
  import draw: *

  rect((0,0), (1,1), name: "rect")
  line("rect.top", (rel: (0, 2)), mark: (start: ">"), stroke: 2pt)
})

Seems to be caused directly by the stroke. With default stroke it looks alright.

Fixed with #314.
