[Qgis-developer] Label backgrounds (shape, SVG, drop shadow)

[Andreas Neumann]

Hi,

I'd love to have these label backgrounds and drop shadows in QGIS 2.0.
Makes sense to me to include this work despite feature freeze since a
major effort was made already to improve labeling in QGIS 2.0.

so +1 from my side.

Thank you for your work, Larry.
