Left and right anchors can't work at the same time with the horizontalCenter. In this case it
makes more sence to remove the horizontalCenter, since the left and right ones also define the
width of the rectangle.

Encountered as I made a failed attempt at solving the issue with rendering transparent support. I tried to order vertices appropriately but failed miserably.
When deleting profiles, the current item is set to null.
The Activate button was checking if the current profile was already active, and disabling the button if it was. But the button was still enabled if the current item is null because isCurrentItemActivated is only true if there is a current item. So to properly disable the button we need to check also if there is a current item.
The onItemsChanged signal can also trigger if the item that matches the toSelectItemName has no quality_changes_group, i.e. a built-in profile.
Probably fixes Sentry issue CURA-43.
It's possible that a profile is no longer in the registry by the time it gets to that point in the list if this clean-up is triggered by the very action of deleting a profile.
Fixes Sentry issue CURA-1T5.
This fixes a very old bug in Cura where sometimes after re-slicing it would display the layer as if you've been going horizontal through the path slider, even if you never touched the horizontal path slider.
This was caused by a tracking flag in the SimulationPass, _switching_layers. This bit of state in the SimulationPass was tracking whether the user is going through the vertical layer slider (True) or the horizontal path slider (False). If False, the nozzle mesh is drawn and lower layers get drawn in a shadowy shader. The state of this flag was being updated on every render by looking at whether the previous render has the same current layer number but a different path index. If so, it changed to False, meaning that it assumes you're going through the paths on a layer and things get shadowy.
However if you slice a different object such that the number of layers stay the same (or at least the current layer) but the number of paths on a layer change (e.g. by reducing Maximum Resolution, or by loading a different model that happens to be equally tall) then it would falsely think you were going through the horizontal path slider.
This change effectively resets this state flag when any layer data is changed in the scene. So if you re-slice, it always goes back to _switching_layers = True.
The side effect is that if you were going through the paths of a layer and you re-slice, you won't end up on the same path even if the number of paths on your current layer didn't change due to the reslice. But I think that is more towards what the user would accept a re-slice to do anyway.
I decided to take a look into this bug because I'm making a script to automatically refresh the screenshots of the Settings Guide plug-in. This script frequently hits cases like this, and it's easier to fix this bug than to work around it in my script.
