The key state can be interesting for mouse events too. Ctrl-Click, Shift-Move. Maybe it is worth to omit the output of state=0.

Agreed, the 4 mouse positions are pretty noisy. Maybe omit root_x and root_y? But mouse position can be relevant for such key events as pressing Ctrl. For example if the mouse pointer points on module name in import statement, pressing Ctrl can convert the name into a hyperling to a file of the module.
