Fix: GPv3: Wrong cursor radius for Tint tool and Weight Paint tools The brush cursor size (the circle in the viewport) of the Tint tool and the Weight Paint tools didn't match the brush radius, because: - The radius unit `Scene` calculation was also applied to the Tint tool brush, while it's only relevant for Draw brushes. - The Weight Paint tools use unified paint settings and the Draw tool doesn't any more since #122886, causing a mismatch in cursor size. In this PR the cursor size is fixed. Pull Request: https://projects.blender.org/blender/blender/pulls/124100
