Test data: fraction_points layer styling

[Benjamin Jakimow]

The default style of tests/testdata/fraction_points.gpkg uses a Text Diagram renderer to show the fraction values per point.
To meet a couple of “good cartographic practices”, these settings should be improved by:

• do not show overlapping text lines
• show number with a consistent number of decimal places (use round function)
• add a glow / halo effect to improve character contrast to background pixels with similar colors

Yes.

Not sure if this is possible. I guess this is a general issue with floating-point precision:

This seams to work, but I’m not sure, if we should do it this way. I would rather create a QGIS feature request for allowing to set the number of digits to render.

For me it is fine as is. Please provide a specific setting you want to have.
