"""Support for simplified access to data on nodes of type omni.graph.ui_nodes.SetViewportMode

Sets the mode of a specified viewport window to 'Scripted' mode or 'Default' mode when executed.
 'Scripted' mode disables
default viewport interaction and enables placing UI elements over the viewport. 'Default' mode is the default state of the
viewport, and entering it will destroy any UI elements on the viewport.
 Executing with 'Enable Viewport Mouse Events' set
to true in 'Scripted' mode is required to allow the specified viewport to be targeted by viewport mouse event nodes, including
'On Viewport Dragged' and 'Read Viewport Drag State'.
 Executing with 'Enable Picking' set to true in 'Scripted' mode is
required to allow the specified viewport to be targeted by the 'On Picked' and 'Read Pick State' nodes.
