UI Main issue is that the UI doesn not respect the Unified Weight/Strength setting (but instead alwasy shows the brushes weight/strength) Was working before, but somewhat missed in rBfb74dcc5d69d. See discussion in T74025 on why the Gradient Tool in its current state is not very user friendly in general, what I think we should do though is at least have the values in the UI respect Unified Weight / Unified Strength since this is what the tool will use internally... ref T74025 Maniphest Tasks: T74025 Differential Revision: https://developer.blender.org/D6900
