applets/pager: Remove animations
The pager applet provides a miniature of the virtual desktop grid and by default, it's placed in the panel. On the other hand, the main purpose of animations is to notify or guide the user through state changes. Due to the location and the size of the pager, the user focus will likely be elsewhere and these animations will go unnoticed.
Unfortunately, these animations have caused some issues too. One was with drag and drop. 463b6798 attempted to address that by dropping x and y animations. That change should have probably dropped width and height animations too because they alone don't serve the real purpose. Another issue is caused by flaws in the animation driving code in QtQuick, which can result in plasmashell triggering constant repaints until the panel that contains the pager is shown again.
So, given the aforementioned issues and small net benefit of these animations, this change drops animations in the pager. It is not the definite fix for upstream issues but it should at least help us mitigate repaint issues that can be observed on setups with the current defaults.
