    Fix scrollbar displayed while splitter maxed out

    * For some reason the table's height is a few pixel longer on Windows so we work around the issue by adding a small offset to the maximum height hint.
    * No idea about MacOS yet but this might need the same treatment.

commit 9f15139
Author: glubsy <[email protected]>
Date:   Wed Jun 24 17:12:59 2020 +0200

    Fix view resetting when selecting reference only.

    * Needed to ignore the scrollbar changes in the disabled
    panel, sine a null pixmap would reset the bars to 0 and affect
    the selected viewer.
    * Keep view as same scale accross entries from the same group.

commit 011939f

Date:   Tue Jun 23 05:03:56 2020 +0200

commit 970bb5e
Author: glubsy <[email protected]>
Date:   Sun Jun 21 01:49:17 2020 +0200

    Add mostly working ScrollArea imge viewers

    * Work around flickering of scrollbars due to
    GridLayout resizing on odd pixels by disabling
    the scrollbars while BestFit is active
    * Also setting minimum column width to work around
    the issue above.
    * Avoid updating scrollbar values twice by using a
    simple boolean lock

commit a706d0e
Author: glubsy <[email protected]>
Date:   Tue Jun 16 21:14:28 2020 +0200

    Implement mostly working ScrollArea viewer

    Using a QWidget inside the QScrollArea mostly works
    but we only move around the pixmap inside the QWidget,
    not the QWidget itself, which doesn't update scrollbars.
    Need a better implementation.

commit b7abcf2
Author: glubsy <[email protected]>
Date:   Wed Jun 10 22:02:08 2020 +0200

    Use native QPixmap swap() method instead of manual setPixmap()

    When swapping images, use getters to hopefully get a reference to
    each pixmap and swap them within a single slot.

commit 8103cb3
Author: glubsy <[email protected]>
Date:   Wed Jun 10 18:23:48 2020 +0200

    Disable unused methods from controller

    * setPixmap() now disables the QWidget automatically if the pixmap passed is null.
    * the controller relays repaint events to the other widget

commit c379791
Author: glubsy <[email protected]>
Date:   Wed Jun 10 01:24:51 2020 +0200

    Controller class to decouple from the dialog class

    The controller singleton acts as a proxy to relay
    signals from each widget to the other
    It should help encapsulating things better if we need to
    use a different class for image viewers in the future.
