How do I create a scrollable popup window?
I can create a dialog that is a popup but it is not scrollable.
The dialog class does not appear to have a scroll option.
Is this where I use a 'panel' class instead of the 'dialog' class?

Thanks! I've pushed a change based on your explanation. I was able to
confirm that it made the `XDG_CONFIG_HOME` environment take effect when
it previously did not, at least.

Racket seems to insist on using ~/.racket as its special place, despite the
apparent fix that added XDG compliance. This happens even when I have
racket folders neatly set up in all my xdg dirs, and clear ~/.racket* every
time.
Stepping through in a debugger, I found the problem was at line 203
I've encountered an identifier binding order issue that only manifests in
the REPL. My current workaround is to use forward definitions followed by
set!s. I've heard rumors that the top-level is hopeless, but I'd like to
try and make this work without unnecessary workarounds, if possible.

Is it possible to effectively display a window with a bitmap background?

If the only way to display a bitmap is in a button, is it practical to size
the button to the entire frame or pane in the frame?
