When transforming Objects, like scaling and rotating we see a custom
drawn cursor at the mouse position. In the default theme this is
entirely black, doesn't change with background color, and can be very
hard to see in some circumstances. This PR uses the same colors as the
text overlays and adds a contrasting shadow to help add some contrast.
