Very ugly ... indeed.

This sounds like the best solution to me ... but I will have to find out
how to do this ;)

It wouldnt look that "nasty" as it does now, but still the "real" map
image would be scaled to small. Since it is alrady hard to see them now,
Id like to have them "as big as possible", without a white border.

No, the relative sizes remains the same, if I use your second
suggestion. What I do is to scale the flag pixmap that its height fits
to the row height. I do not change the ratio.
