Breaking: #101647 - Unused graphical assets removed from EXT:backend

See forge#101647

Description

The TYPO3 system extension "backend" accumulated many graphical assets over the years that became unused piece by piece.

The following icons have been removed from the Icon Registry:

  • status-edit-read-only
  • warning-in-use
  • warning-lock

The following assets have been removed from the directory EXT:backend/Resources/Public/Images/:

  • FormFieldWizard/wizard_forms.gif
  • clear.gif
  • filetree-folder-default.png
  • filetree-folder-opened.png
  • Logo.png
  • pages.gif
  • tt_content.gif

Impact

Calling any of the removed icons from the Icon Registry will render the default icon. Accessing any of the removed files directly will lead to a 404 error.

Affected installations

All extensions using the removed icons and assets are affected.
