Revert "Ensure arcTo (SVG) ends at the targeted point"

This reverts commit 31143100ee2a5e95a552b3d9ed559b068c8df76b.

Reason for revert: need to guard this, to stage changes to test images

Original change's description:
> Ensure arcTo (SVG) ends at the targeted point
> 
> Floating-point errors in the calculations in arcTo can cause the final
> point to differ significantly enough from the supplied target point that
> a subsequent 'close' operation inserts a lineTo to close the curve. This
> can result in bad miters on curves with thick outlines.
> 
> The fix is to ensure that the final point used is *exactly* the point
> that was supplied.
