This function goes and looks for the icon file. If the icon is not an absolute filename, this will look for it in the standard places. If it can't find the icon, it will return `NULL`

`icon_theme` : | a GtkIconTheme
`icon` : | icon name, something you'd get out of the Icon key
`desired_size` : | FIXME
`flags` : | FIXME
Returns : | A newly allocated string
