Internally our "Time" mouse cursor, it comprises up to four digits in a 2x2 grid. With each digit being just 7x7 pixels this is very small on high DPI displays. This PR adds an alternative that shows 12x14 pixel digits, shown when the UI Scale > 1.45. It also changes both small and large versions to not show a solid black background for empty digit positions. Pull Request: https://projects.blender.org/blender/blender/pulls/132767
