Yes, but if you are using an svg to start with you don't have much detail to
lose, but your point is well taken. Png is superior, but it is not as widely
used as jpg. I agree that xcf is a good format, but the file sizes are huge
in comparison to either png or jpg with png being larger than jpg. It is a
trade off files size for detail, but you need the detail to begin with to
make the larger file size worthwhile. Svg does not support the colour range
and detail to warrant it, IMO. Also you cannot send an xfc to just anyone.
They need to be a GIMP user or it is useless.
