 * major version. However, breaking changes may come, and result in a major
 * version bump. To help migration, the `KALEIDOSCOPE_API_VERSION` macro can be
 * used to check the major version provided by the Kaleidoscope we are compiling
 * against. This can be used to error out with a helpful message, or change how
 * the API is used - it is entirely up to the plugin or sketch author. The point
 * of this macro is to let them easily check the version.

 * printed.
 *
 * Done so that a new API version would result in a helpful error message,
