How to move a link #317

Hello TheDmd,

first of all, thank you very mush for this great lib im using now since many years (Mostly in Lumo)

Its not a bug, just a request for a way to do a thing.

I would like to add a easy way to move a link from a pin to another pin. like redirect a link.
In my case an output pin can have many links, but only one link can be connected to input pin.

so i would like to by just click on a connected input pin redirect the link to another pin.

if im not bad, i seen a comment somewhere of you where you speak about that (or i dreamed, not found back the comment)

Its a feature who is already available or not ?

for add a link im using this code :

if (nd::QueryNewNode(&slotId)) {
    auto slot_ptr = m_findSlot(slotId).lock();
    if (slot_ptr->getDatas<ez::SlotDatas>().dir == ez::SlotDir::INPUT) {
        showLabel("+ Redirect link", ImColor(32, 45, 32, 180));
    } else if (slot_ptr->getDatas<ez::SlotDatas>().dir == ez::SlotDir::OUTPUT) {
        showLabel("+ Create Node", ImColor(32, 45, 32, 180));
        if (nd::AcceptNewItem()) {
            m_doCreateNodeFromSlot(slot_ptr);
        }
    }
}

but move a already existing link is a different behavior.

if i click on a input slot, i would like to have the link from the pin who was connected to the input pin i clicked on.

you know is there is way to specfiy the pin id for the start of the link drawing ?

maybe a function to add for set the the pins m_StartPin and m_EndPin for this particular case ?
