## Demos
### DemoProxyProgram01
[source code](src/jvmDemo/kotlin/DemoProxyProgram01.kt)
Demonstrates how to use a proxy program inside a [viewBox],
how the main program can access its variables and methods,
and execute its `extend` block by calling its `draw()` method.

### DemoProxyProgram02

[source code](src/jvmDemo/kotlin/DemoProxyProgram01.kt)
### DemoProxyProgram02
Demonstrates how to use two proxy programs and
toggle between them by clicking the mouse.
programA draws a circle and can be moved by pressing the
arrow keys.
programB draws a ring located at the current mouse
position.
Note that programA keeps listening to the key events
even if programB is currently displayed.

### DemoUpdate01

[source code](src/jvmDemo/kotlin/DemoProxyProgram02.kt)
### DemoUpdate01
Demonstrates how to create a viewBox with an interactive 2D camera and
display it multiple times.
Instead of calling the viewBox's `.draw()` method multiple times,
we call its `.update()` method once, then draw its `.result`
repeatedly, in a grid of 4 columns and 4 rows.
The camera's initial rotation and scaling are specified as a transformation matrix.
To control the camera use the mouse wheel and buttons on the top-left view.

### DemoViewBox01
[source code](src/jvmDemo/kotlin/DemoViewBox01.kt)
Demonstrates how to draw multiple view boxes. The first two feature
interactive 2D cameras, the third one uses an Orbital 3D camera.
All three can be controlled with the mouse wheel and buttons.
The `shouldDraw` viewBox variable is used to avoid re-rendering the view
unnecessarily when the camera has not changed.
