An additional comment:
after zooming in greatly, it can be seen that a faint single-pixel line *is*
being drawn for both an added line and the help lines, but at normal zoom they
disappear.

A single pixel line shouldn't disappear at normal zoom, so that is the primary
bug that should be fixed, but perhaps another improvement would be to make the
help lines simply use a thicker line (like the grid lines which do show
correctly at all zoom levels). And perhaps the default line style should use,
say, a 0.5 mm line and not a 0mm line.

> Description:
> On a recent macbook (e.g MacBook Pro 2108) with a high resolution display,
> zero-width lines disappear.  Zero width lines are meant to show as a single
> pixel (thinnest possible width) line.
> This is a problem as new lines in Draw default to zero width, and also help
> lines in Draw don't show as presumably they are being drawn zero-width.  
> 
> Steps to Reproduce:
> 1.Open draw to get a new canvas
> 2. Select line drawing tool and add a line to the canvas
> 3. Line will be invisible
> 4. Go to styles and right click on default, and click modify
> 5. Change line width from zero to 0.5 mm. Now line will appear.
> 6. Enable view|grid and help lines| help lines while moving
> 7. Drag line or other shape on canvas- help lines do not show.
> 
> Actual Results:
> A default line does not display on high resolution MacBook displays as zero
> width lines are incorrectly not being shown as single pixel wide lines.
> 
> Expected Results:
> By default adding a line using draw should show a thin line.
> 
> 
> Reproducible: Always
