theme: Make spinner drawing start with the solid line

Previously, for i == 0, we were drawing the translucent line first.
However, people reading the code would always assume the solid line is
indicated by the current step. So make the code do that.

Note that the spinner now rotates in the wrong direction. This will be
fixed in a future commit.
