Re: [PATCH] SHAPE_ARC tests
It looks like your indention is 8 spaces for the test case vectors.
Everything else looks indented correctly.
The old drawing code could be compiled to actually draw the bounding box
which was rather handy when messing with bounding box code. I guess
that didn't get implemented in the new drawing code. The tests should
hopefully take care of that.
