WaypointRenderer: if MAT, draw all Turnpoints as Task points

They were hard code as black which is hard to read when the
background is dark.
TopographyFileRenderer: Suppress drawing duplicate topography labels

With high resolution map files, split map shapes cause duplicate topography labels
to be drawn, which overly clutters the screen.

This change suppresses drawing these duplicates, meaning that all topography labels
that are drawn are unique.
Util/QuadTree: add missing CanSplit() check

The check was present in Add(), but not in Optimise().  This could
lead to an infinite recursion.
