Use the same line dimensions as the profile, on the planner.

The Planner should be 'almost' like the profile, with the possibility
to use the mouse and keyboard to input a new plan, so this is a bit
of 'getting there.' I don't like too much code duplication but since
the current Profile Graphics is a crude cut-and-paste from the old
Cairo backend, it's easyer to start from scratch and have it well
organized as Qt code.
