Straignt lines are wonky

Is this solved yet somehow? Is there some option I’m not seeing? It seems to be marked as completed here: Line algorithm · Issue #1944 · aseprite/aseprite · GitHub
But the issue persists as of 1.3.17-beta2.

In the issue you linked it says it’s only enabled in one of these cases:

  1. When the snap angle modifier is pressed: Shift key in Line tool, and Ctrl modifier when Pencil+Shift key is used to draw straight lines
  2. When the snap to grid is enabled (which it makes sense to create perfect lines that match the grid tiles)

Seems like it might be better as just a toggle in the line tool.

Oh. Ok. So how do you make it snap to the 17.7 angle you need for exact 3:1? It only seems to snap to 2:1 or 1:1 for some reason.
