Handle more commands in Execute()
Find ourselves an ID_APP_ABOUT replacement
I think we want to minimize from the menu?
Nope, we do want that to actually exit.
Can we shrink the view?
Nope, that's too early
Revert that experimentation
Can we use a dummy status bar?
Revert "Can we use a dummy status bar?"

This reverts commit 7bc03a635c3766fd8c377a26488691afeabfed76.
A new strategy

More sizing updates

Have the main frame grab the ribbon height while calculating the
layout, not just (?) on sizing events.

Send a WM_RECALCPARENT message from the ribbon when its size updates.
Seems okay in just RecalcLayout

May not need OnCreate?
Use custom message for ribbon resize

Trying to reuse something extant seems to cause buffer overruns.
