In the above case there's a 45deg-rotated-around-origin space in which
I draw a 50deg circle around origin. Shouldn't the box be 100x100
either way? The 141x141 box looks like the result of computing the
100x100 box, transforming it by current matrix and then computing the
bounding box of that box again, resulting in the 141x141 box I see.
