Valid Begin Cursor Demo
The demo exhibits a GraphComponent where graph editing is configured to
show different cursors depending on which gesture is valid to begin at the current
location considering the currently pressed modifiers.
Some input modes were configured to only begin when a specific modifier is pressed to
distinguish which gesture should start.
