[Qgis-developer] inconsistency of new "fill ring" icon

[Denis Rouzaud]

Hi,

I have noticed that the new icon for fill ring was not really consistent 
with the rest (no new part, polygon was not fully drawn).

I took the opportunity to transform digitizing icons to SVG to be 
consistent with the previous work on layer icons.

Here is the pull request

Please comment.

Cheers,

Denis
