Since 2.80, the 3D Cursor is actually 3D, but it is still not clear
which way it points.
To improve this, the following style tweaks were done:
- Use theme axes colors for the 3D Cursor lines, a bit desaturated.
- Draw the negative axes a little darker, to tell at a glance its
direction.
- Replace the red/white lines with black/white for improved contrast
and to not conflict with X axis colors.
- Make it over all smaller in size, since it's already prominent by its
colors.
