Stipple fill dot properties

[oertz]

Stipple fill invokes a pattern of dots ... but what does a dot looks like ? Probably not what Table 22 Dot class default values says ?White color ? 10px size ? And by the way, how to define the color of the dot ?

It seems using the stroke ? @jerstlouis @maxcollombin

@oertz @ebocher in the original idea, stipple fills are one pixel dots, and there was no control on the dot size, only on the stipple fill density.

the color of those dots I believe was simply fill.color, with outside the dot being transparent

[oertz]

@jerstlouis : ok so no size control and transparent outline. But fill.color is rather to set the solid filling of a polygon, for the stippled dots may we need to set a fill.stipple.color ?
