Revert to old graph edges positioning (added an option) #10430
Added option that reverts to old method of positioning edges. This option is on by default, since old edges were better in most cases. I will continue and try to finish the new edges before release.
This is better than reverting my last graph edges pr since it fixed other small things too (like enlarging of nodes with many edges, and some improvements on vertical layout)
I had changed a test in that pr, so here is that test reverted: https://github.com/radare/radare2-regressions/pull/1364
ALSO I included a typo fix in canvas.c that I forgot in my last pr
