[Qgis-developer] "No symbol" renderer... thoughts?

[Mathieu Pellerin]

I'd vote for the last option as it'd be compatible with rule based
symbology, which could be useful when coupled with the [x] show layer count
(simple eg creating a ELSE rule with a no-symbol layer to keep track of nb
of features not rendered.).
