better handle moving points
This should hopefully address #5. I'm removing some constraints from manhattan lines, rectangles and squares.

In particular, circles/squares/rectangles and point labels can overflow a drawing. -* Insufficient handling of constraints when moving points. For example, if you - draw a manhattan line and then move one of the points, you may not be able - to hover on it anymore. - - There's two broad ways to fix this. The first is to relax constraints, - switch the manhattan line to not be manhattan. The second is to try to - maintain constraints. Either constrain the point to only move along one line - (but what if it's connected to two manhattan lines?!), or constrain the - other end of the line to move alongside. I'm not sure yet which would be - more useful. Getting into constraints would also make the program more - complex. - - Bottomline: at the moment moving points connected to manhattan lines, - rectangles or squares can break drawings in subtle ways. - * Touchpads can drag the mouse pointer using a light touch or a heavy click. On Linux, drags using the light touch get interrupted when a key is pressed.
