RT-20302: Consider changing picking behavior of dashed strokes

Definitely more expensive than solid stoke case. Depends on how often we 
expect somebody will need dashed-stoked objects picking and how much 
information we cache with such strokes.

Currently an object is picked even when the mouse click happens in the non-filled parts (inside spaces) of the dashed stroke (stroke dash array and dash offset have no impact on picking). With RT-19994, this can create an unexpected situation, when a Shape is picked inside stroke spaces, but if it is used in a CAG operation (for example Shape.intersect(shape1, shape1)) the resulting Shape won't include the spaces and so won't be picked inside of them. To get consistent behavior I propose not to pick the spaces inside object stokes.
