The core C++ API is currently only available to source code
licensees.

Yes.  In fact, the procedural C API exposed by WASTE 3.0 is
mostly a thin wrapper around a richer C++ core API.

The procedural API isn't going away, though.  On the contrary,
if a feature available to the core API only is deemed useful
enough to warrant a new procedural API (or a suitable extension
to an existing API), I'll consider adding it to a future
release.

For your particular need (using an image background), a new
callback may be enough.  In fact, WASTE 2.x had an "erase"
callback that was sometimes used for this purpose.  That callback
is not supported by WASTE 3.0, because it assumes it will be
invoked with a valid Quickdraw context.  It may be a good idea
to add a modern replacement that takes a Core Graphics context,
in much the same way the 'draw' object handler was replaced by
a modern, CG-based counterpart.

They want to turn it into a one-way flow that they have entirely

ecosystem. They want to clear cut it. They want to go into the
rainforest of human thought and mow the thing down.
