REVISION SUMMARY D11848 <https://phabricator.kde.org/D11848> started out with the aim to remove the delay on Kickoff tab switching, but this proved contentious because it can cause user frustration over accidental tab switching when moving from the tab bar to the list view at angle, grazing another tab. This patch implements a triangle filter to get the best of both worlds. When the mouse motion vector is within the triangle from the vector starting coordinate pair to the relevant tab bar corners, the original 250ms delay remains in use. When the vector is outside the triangle, tabs are switched immediately - improving even over the 50ms delay proposed in D11848 <https://phabricator.kde.org/D11848>. Care is taken so that tab switching is always immediate when the tab bar is freshly entered, e.g. moving from the panel to Kickoff. As a small advantage this removes a MouseArea item from each tab button.
