Description

Curved labels in city streets are often illegible if the angle is upwards or ugly if the angle is downwards.
The option 'Maximum angle between curved characters' only prevents the label being drawn at all.
What we need is an option to specify that the curvature is based upon the mean line, not the base line. Furthermore we need to be able to specify an extra amount of spacing depending upon the angle between two characters.
Alternatively the curvature could use the base line if the angle is downward and the ascender line if the angle is upward. However the issue of ugly labeling remains.
