Breaking: #60559 - Dropped Backend Login Options

See forge#60559

Description

Handling of $GLOBALS['TBE_STYLES']['loginBoxImage_rotationFolder'] and $GLOBALS['TBE_STYLES']['loginBoxImage_author'] was dropped.

Impact

Setting those options has no effect anymore.

Affected installations

These options had no effect with standard core internal login screen based on t3skin for a long time already. Instances are only affected if a 3rd party extension is loaded that changes the backend login screen and operates with these settings.

Migration

Remove these options and their usage from the affected 3rd party extension or unload the extension.
