📄 Description

The Sample method has an offset parameter which we can use here.
The result is not identical to the old shader, as the older shader
used the height of the terminal for drawing horizontal edges and so
the result looked way fatter than it was seemingly originally intended.
On my 150% scale display I found an offset of +/- 2px to produce an
acceptable result, although in the future it might be worthwhile to
make the offset dependent on the UI scale.

Closes #14953
