[Drawkit] Selection behavior with groups

[Brad Larson]

One thing I encountered today was a difficulty in moving a large group  
selection, which might require a change in the way that knobs are  
selected.  When you select an object with a large number of features,  
you normally can move that group selection by clicking and dragging on  
any of the features within the selection.  The problems come in when  
you have a group selection and click and drag on a knob from one of  
the selected objects.  It's been my experience in other draw programs  
that this would also cause a dragging of the whole selection, but in  
DrawKit that currently causes the selection to be lost and for you to  
edit the object by dragging that control point.

This really causes a problem with groups containing many fine  
features, as often the knobs will be the only thing in the selection  
that you can click on to move it.  For example, in the Beta of  
SonoDraw, try loading the sample PCBExample.pattern, enlarging the  
canvas, selecting all objects, copying and pasting another group of  
objects, then moving the selection.  It is very difficult to do unless  
you zoom way in and select a non-knob part of one of the lines.

This seems like something that is fundamental in the functioning of  
the DKKnob, so I didn't know where to start with modifications or even  
if they were  desired.  Do you prefer this method of selection /  
editing?
