[0.17.47] rendering.draw_line(): some lines disappear from screen depending on player position/zoom

[Creidhne]

What's happening:

When using rendering.draw_line to draw a set long & almost parallel lines, some lines aren't rendered on screen. Moving the character or zooming in/out may change which lines are displayed/hidden. Sometimes no lines are rendered at all.

Expected behaviour:

Steps to reproduce:

1. Create a new game
2. Run the following in-game command:

   Code: Select all

   /c for i=1,100 do rendering.draw_line({from={i,0},to={1000+0.1*i,1000},color={g=1,a=1},width=1,surface="nauvis"}) end

3. Walk on the right while changing the zoom level

Thanks for the report, fixed for the next version.
