Line Tool: preview line size (width, height) like Rectangle Tool in top-bar dimension hint area

[hsandt]

I was drawing precise lines for a perspective work and noticed that unlike the Rectangle Tool, and Line Tools in other graphics software, the Line Tool doesn't show a live preview of the current dimensions (width, height) in the top-bar area, where it only shows end point coordinates and angle.

It would be helpful to show the line dimensions too.

The most simple convention is: only positive numbers independently of line direction, start at (1,1) for a single pixel.

You can also try other conventions like negative numbers when going top-left, however this may mess up with the convention of starting at (1, 1) (because then people expect relative numbers, so starting at (0, 0) and (-1, -1) when going 1px toward top-left).

Alternative conventions are good for me as long as they are precisely indicated with icons or labels (I often mess up between rectangle size and rectangle top-left to bottom-right offset, which differs by (1, 1) px in different graphics software, but it's OK as long as it's consistent with the rest - in this case, Rectangle Tool is already using always positive (1, 1) convention so it's good to keep for lines.
