=begin
APIs that haven't been encountered in a previous sample apps:
- args.inputs.mouse.click: This property will be set if the mouse was clicked.
- args.inputs.mouse.click.point.(x|y): The x and y location of the mouse.
- args.inputs.mouse.click.point.created_at: The frame the mouse click occurred in.
- args.inputs.mouse.click.point.created_at_elapsed: How many frames have passed
since the click event.
Reminder:
- args.state.PROPERTY: The state property on args is a dynamic
structure. You can define ANY property here with ANY type of
arbitrary nesting. Properties defined on args.state will be retained
across frames. If you attempt access a property that doesn't exist
on args.state, it will simply return nil (no exception will be thrown).

# This code demonstrates DragonRuby mouse input
# To see if the a mouse click occurred
# Use args.inputs.mouse.click
# Which returns a boolean
# To see where a mouse click occurred
# Use args.inputs.mouse.click.point.x AND
# args.inputs.mouse.click.point.y
# To see which frame the click occurred
# Use args.inputs.mouse.click.created_at
# To see how many frames its been since the click occurred
# Use args.inputs.mouse.click.creat_at_elapsed
# Saving the click in args.state can be quite useful
