Drawing rectangle or cirle outlines

[nevraw]

I understand how we fill rectangles & circles, but how do we just draw just the outlines?  

Filling a smaller rectangle, in the background colour, within another would achieve this, but that doesn't help when wanting to have overlapping rectangle outlines.  Same with circles.

You'd need to use grayscale images, filled with a color.

I wondered if that was the case.

So, we are going to make heavy use of images and much less use of rectangles than on Pebble watchfaces.

Circle outlines will still be possible using arcs.
