[Qgis-developer] function to have text smaller (for labeling)

[Denis Rouzaud]

Hi all,

I wonder if it would be feasible to create a function to be used in an 
expression in order to alter the font of labels.

My use case is that I would like to have a smaller line after the main 
one on the label.

I don't think that rule based labeling is the right approach since that 
would be 2 distinct labels.

Do you think it would be acceptable or it is too much of hack to have 
such thing in core ?

Best wishes,

Denis
