A bit later, I answered:

A better way is to use <ConfigureNotify> instead of <ResizeRequest>.

ResizeRequest appears to be *instead of* the regular resize action.
Also, the ResizeRequest action observably gets called when the window is
merely moved on the desktop, even when the window's size hasn't changed.

By contrast, with ConfigureNotify the regular resize code is still run
and the translation action is called when the width or height changes,
but not when the window is just moved.
