Plugins + Scripts Mouse Control Overhaul

Custom hover selection:​

• Choosing the closest controller to mouse position in screen space using mouse location and radius which depends of fov and distance to controller.
• Scale 1.0 is about radius of circle inside CUA's rectangle controller.
• Ignoring hidden controllers (default implementation allowing to drag and select hidden controllers).
• Ignoring default style cycle through few near controllers (using C button) because it is garbage and very strange idea.

Drag Activation Distance:​

• Default drag activates when mouse moves quite far away from previous position in one tick.
• This one checking distance from pressed position to current mouse position in screen space.

Controller's name:​

• Hovered controller's name is showing as help text at left of main hud.

Changeable hotkeys​

Implemented MacGruber's PowerHandles logic with some tweaks:​

• Position/Rotation handles are hidden if Show hotkey is assigned, visible if holding hotkey.
• Local/Global axis mode can be toggled by ToggleAxisMode hotkey and switched by HoldAxisMode hotkey while holding.

Small Tweaks:​

• Gizmo is deselecting if mouse on GUI.
• Dragging radius of selected controller covering full gizmo circle if RotationHandle is active, if not it is using SelectedDragScale value.
• Stop dragging if application window lost focus.
• Escape button by default cancelling current selection or closing menu if nothing selected.
• Fixed MacGruber's hack to make Empty atom's sphere renderer visible only when collision is enabled and current menu is SelectedOptions (like default one).
• Set selected controller icon for 0.5 scale, because default one is huge (maybe need to add it into settings).

Hints:​

• If you don't plan to use FreeMode (Tab button) and you are using Keybindings plugin, you can remove this button and assing Tab for ToggleAxisMode.
• For high resolution monitors you may need to increase DragActivationPixelDistance.

Knowing Issues:​

• LookAtTrigger does not work.
  • Cannot use default variables and methods.
  • I haven't seen anyone use it, so likely you will not notice it.
• Other modes with controller selection like "Select Parent Atom From Scene", "Select Link To From Scene", "Select Force Receiver From Scene", "Possess And Align" are using default selection.
• I don't like how handler's grid mode works (it is just rounding all coordinates even when you moving along one axis), so i disabled it.

Little Issues:​

• Cursor blinking when I am trying to hide it every frame, so I don't hide it at all.
• Switching to FreeMode sometimes causes the controllers to be hidden for one frame.
• Switching ShowHiddenAtoms causes the controllers to be hidden for one frame.
• In FreeMode when you move cursor above gui, a blue circle should be visible.
