I am referring to the program icon appearing when the program is running. I think the current size is 48 x 48.

I use Kubuntu which offers a plethora of display screen options among them a wider task manager bar along with an ability to show a bigger icon in that bar, it appears to be a zoom out like functionality. The problem is that the icon is just to small and looks like shit when displayed magnified, the straight diagonal lines turn into steps. I tested a quick GIMP change to 150% of original size and it displays fine.

So my request is can you embed a bigger icon in the program please.
