Don't assume the dialog is mode-less and call Destroy() from within a
dialog method. This will most assuredly crash if the dialog is shown
modally or quasi-modally.
Don't leak memory for mode-less dialogs created on the stack. Make sure
when the parent frame window is closed that all mode-less dialog memory
is cleaned up. Dialogs are not child windows like controls and toolbars
so their memory does not automatically get cleaned up when the parent
window is destroyed.
Do not directly access frame parent window's pointer in dialog destructors.
Apparently the tear down order when destroying mode-less dialogs is not
guaranteed so the parent window may get deleted before the dialog causing
a crash when accessing the parent window pointer from the dialog dtor.
Do not close mode-less dialogs in the parent frame's destructor. This
doesn't guarantee that the dialog(s) will be destroyed before the parent
but it may reduce some careless mode-less dialog event handling in the
future.
1) The highest priority zone that a via/pad collides with "owns" its
connectivity state. Once set, lower priority zones cannot change it --
and in fact, if they would have connected to it are forced not to.
2) The connectivity state goes with the zone fill state, and therefore
must be saved in the file.
3) Display of remove-unconnected's pads is no longer done in GetViewLOD()
(which isn't called for selected items), and is instead done in PCB_PAINTER.
This allows us to draw the full pad in outline mode when a via/pad is
selected which would otherwise only show the hole.
4) Note that in some cases this will still generate DRC errors -- in
particular when a via nearly collides with a higher priority zone it
won't get "owned" by that zone and may therefore have insufficient
clearance if said zone concludes it's unconnected and a subsequent
(lower priority) zone connects to it (causing it to now become flashed).

When tuning high speed traces, you may need to extract data per layer
rather than just the summary as signal speed varies based on dielectric
and trace type
Rather than measuring the total via height, measure from the entry to
exit track height to get a more accurate distance
(cherry picked from commit 57de5a6b65)
They don't define a KiCad string class, so the header file name was
somewhat misleading. But the fact that they didn't match definitely
made coding more difficult.
