[Qgis-developer] SVG-Icons instead of PNGs?

[Andreas Neumann]

 Hi Robert,

 Thanks for the reply.

 Do you have a side-by-side comparison of SVG vs. png and the rendering 
 quality somewhere? I wonder if this is still an issue and if it is - how 
 much of a problem it really is.

 Having just one icon size instead of n different sizes also has a lot 
 of advantages. Think about all the new high-dpi devices. These would 
 benefit a lot from SVG instead of PNG.
