Platform specific notes regarding save dialog filters:

• On MacOs
  • If filter is set, all files will be grayed out (no matter the extension sadly)
  • If user does not type an extension MacOs will append first available extension from filters list
  • If user types in filename with extension MacOs will check if it exists in filters list, if not it will display appropriate message
• On GTK
  • It only filters which already existing files get shown to the user
  • It does not append extensions automatically
  • It does not prevent users from adding any unsupported extension
• On Win:
  • If no extension was provided it will just add currently selected one
  • If selected extension was typed in by the user it will just return
  • If unselected extension was provided it will append selected one at the end, example: test.png.txt
