- Not all Qt::CursorShapes are supported on all platforoms
- e.g. on Wayland (Ubuntu 24.04) Qt::SizeAllCursor is not available and
falls back to its arrow cursor
- added built-in Crosshair and Move cursors, so that they should be available
across all platforms
- Redesigned existing object creation cursors
- Crosshairs are now 3-pixels wide
- Added white outlines to all cursors to aid in visibility against diverse
backgrounds
