Overrode the draw() method of the MultiTouchDrawable in SiteMap instead of 
painting the grid in the getDrawable() method of SiteMap.

Why?

Drawing a bitmap first and then scaling it in the draw() method is WAY slower 
than directly drawing on the already scaled canvas. Moreover, this way 1-pixel 
lines stay 1-pixel lines at every scale factor. That's nice!
