gEDA-bug: [Bug 700841] Re: gschem: during selection invisible attributes extend component bounding box

[Peter Clifton <pcjc2@xxxxxxxxx>]

The patch is using a sledge-hammer to crack a nut..

I'm sure we can nail down the specific failing case and recalculate the
bounding box where it is made invalid.

We are probably missing a call to o_bounds_invalidate() somewhere in the
attribute handling. (Guessing based upon your investigation above)

Title:
  gschem: during selection invisible attributes extend component bounding box 

Status in GPL Electronic Design Automation tools:
  Incomplete

Bug description:
  Intermittently gschem gets into a state when promotable (visible) attributes within a component extend component's bounding box used for selection calculations.
In such cases component might not be selected even if selection rectangle encloses component's graphics and pins.
It is also possible to select the component by clicking on an empy space far away from it - because in the symbol file a visible attribute is located at that offset.

It is expected that components can be always selected by drawing a selection rectangle that encloses all graphical elements and pins.

When the bug occurs, toggling "show/hide invisible text" restores correct behavior.
