[eafton]

This patch adds an icon (warning, icon, information) to message boxes on the X11 backend.

I have decided to redo the positioning/styling code, any opinions?

This doesn't add much visual style. Maybe we should use an icon circle background with colors to indicate severity? This more closely matches other platforms.

I am looking into it.

I implemented the suggested changes and switched to a circle background, thoughts?

It doesn't look great to me. Maybe it makes sense to build in actual icons?

What about using coloring the icons in with blue, red, yellow, etc and drawing an outline?

Is this any better? I think it wouldnt be bad if we used a light color scheme for the widgets.

That's not bad. Can you check other platforms to see what their icons look like? It might be worth checking zenity, as that's closer to what people would expect on Linux.

After checking, I decided to add a small shadow to the icon for increasing contrast, opinions?

@slouken I decided to tweak the palette some more and bevelling to the buttons, thoughts?

This seems fine. @icculus, thoughts?
