I agree. I didn't add any filtering to the GTK version yet, because I
couldn't come up with a good way how to pass the info yet. Basically, my
initial idea was like:

"*.png;*.jpg;*.*"

This would have added a drop-down box with those three choices, so
either you would get only .png files, only .jpg files, or all files.

However, what makes more sense would be if I get a drop-down box with:
Pictures (*.png;*.jpg)
All Files

So if it is to be passed as a single string, it might look like:

"Pictures(png;jpg);All Files(*)"

But it's a very minor feature, so not sure it's worth adding a parser
for such filter strings.
