if i draw something at
`\draw [thick] (10,10) rectangle (11,11);`
Then decide I want it at
`\draw [thick] (2,2) rectangle (3,3);`
I have to go back and edit each point, which seems long and I've
only got two points, if there were many then it could take ages to
rearrange something. Is there somekind of tikZ workflow I'm unaware of ?
