* In some cases, the function dump_IFD() in core/pe/exif.py assigns a string instead of an int as "values".
* This value is then used as _cached_orientation in core/pe/photo.py in _get_orientation().
* The method _plat_get_blocks() in qt/pe/photo.py was only expecting an integer for the orientation argument, so we work around the issue for now by ignoring the value if it's a string.
* Whenever the Result Window already existed and its tab was in second position, and if the ignore list tab was in 3rd position, asking to show the Result window through the View menu would add a new tab and push the Result tab to the third position (ignore list tab would then become 2nd position).
* Fix view menu Directories entry not switching to index "0" in custom tab bar.
* The close button on custom tabs cannot be hidden on MacOS for some reason.
* Prevent the directories tab from closing if the close button was clicked by mistake
* Use QGroupBox to keep items together on the display tab in the preference dialog just like for the other options.
* It is probably not be necessary to keep these as class members
* It seems that stretching the last section automatically is a bit inconvenient on MacOS as it will grow beyond the window border.
* Keep it as it was before for now until a better solution is devised.
* We use GroupBoxes to group items together and surround them in a frame
* Remove separator lines to avoid cluttering
* Adjust columns and their stretch factors for better alignment of buttons
* On Linux, even with 1 pixel size, the button is filled entirely with the color selected
* On MacOS, the color pixmap stays at 1 pixel so we hard code the size to 16x16
* Add Directories to the View menu.
* View menu items should be disabled properly depending on whether they point to the current page/tab.
* Keep "Load scan results" actions active while viewing pages other than the Directories tab.
* Restore the details dialog dock position if it was previously docked (i.e. not floating).
* Since the details_dialog instance was not deleted after closing by default, the previous instances were still saving their own geometry. We now delete them explicitely if we have to recreate a new instance to avoid the signal triggering the callback to save the geometry.
* Since restoreGeometry() and saveGeometry() are only called in our QDockWidget, it should be safe to modify the methods for the Preferences class (in qtlib).
* While the details dialog is opened, if quit is triggered, the error message "'DetailsPanel' object has no attribute '_table'" is reported
* A workaround is to cleanly close the dialog before tear down
* When using the Ctrl+I shortcut or the "Details" button in the Results window, toggle the details dialog on/off.
* This works also while it is docked.
* It seems that matchblock.getmatches() returns too early and the (multi-)processes become zombies
* This is a workaround which seems to work by sleeping for one second and avoid zombie processes
* Just like the Windows package function counterpart, better abort building the package if the help and locale files have not been build instead of ignoring the error
* Buttons display the color currently in use
* Result table uses selected colors accordingly
* Keep items aligned with GridLayouts in preference dialog
* Reordering of items in a more logical manner*
* On Windows and MacOS, no idea how themes work so only allow Linux to use their theme icons
* Internal icons are used by default on non-Linux platforms
