Feature request: do not render 0 values

[frafra]

Hi,
pgf-pie tries to render 0 values, and this creates graphical glitches and text written on top of other labels. It would be good to have an option to disable these values and remove them from the legend.

Why don't you just remove the 0 slice from the specification?

Filtering out zero values can be seen as a special case of a more general filter, like the /pgfplots/x filter in pgfplots. But since pgf-pie is so light, I would suggest to do all these pre-processing operations (filtering values, merging small values, etc.) manually.

Sometimes you have many graphs with the same classes, but data has some zeros.

Would it still be considered a rendering problem if labels overlaps with non-zero values?

It's something neither tikz (excluding graphdrawing lib) nor pgf-pie provides auto solutions.
