APIs that haven't been encountered in a previous sample apps:
- args.outputus.borders: An array. Values in this array will be rendered as
unfilled rectangles on the screen.
- ARRAY#inside_rect?: An array with at least two values is considered a point. An array
with at least four values is considered a rect. The inside_rect? function returns true
or false depending on if the point is inside the rect.
```
# Point: x: 100, y: 100
# Rect: x: 0, y: 0, w: 500, h: 500
# Result: true
[100, 100].inside_rect? [0, 0, 500, 500]
```
```
# Point: x: 100, y: 100
# Rect: x: 300, y: 300, w: 100, h: 100
# Result: false
[100, 100].inside_rect? [300, 300, 100, 100]
```
- 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.
