Detailed Description

Converts mouse clicks into mouse drags.

This block receives mouse_click messages, which specify the position of the mouse button (up or down) and the coordinates where the user pressed/released the button. Once a down and up mouse_click message has been received, a mouse_drag message is sent. This specifies the start and end coordinates of where the mouse was dragged.
