Making a better (mini) World (map)

Previously, we had a minimap which was created by drawing our primary scene on a render target, then drawing that scene to our display twice: once at display size and again scaled to about 1/8 size.

Unfortunately, scaling down the render target can result in some of the lines not being drawn properly due to pixels scaling to less than 1 pixel in size.

To rectify this we now draw our scene twice:

Once at full scale for normal interaction

Once at 1/8 scale to give us a minimap.

This can lead to some slight distortion in the minimap since lines are much wider than they are in the main display, but the effect is much smoother.
