I already cleaned it up without altering the behavior.  It probably isn't worth investing more time in.  The whole binary CSS code is AFAICS basically only used to create binary versions of the FX standard css files, like `modena.css`, by calling the main method of `Css2Bin` during the gradle build.  This probably saves some time for JavaFX startup as the binary version will load faster than the text versions (or so I hope, I didn't check if that's true).  I have doubts it is used anywhere else, so although this has creeped into a few public API's, it's practically for internal use only.
