Redefine includegraphics* (starred version)

Question

I have this code:
setlength{fboxsep}{0pt}
letincludegraphicsbakincludegraphics
renewcommand*{includegraphics}[2][]{colorbox{white}{includegraphicsbak[#1]{#2}}}

How can I make it work with the starred version of includegraphics?
I get this error if includegraphics* is used in the file:
! LaTeX Error: File `*' not found.

The code shown would also disable the second optional argument of includegraphics
The second optional and the * form are both really for the graphics package interface which is really not used much so one possibility would be to ignore this aspect. (The star form just adds clip to the supplied keys, so it is more natural to use includegraphics[clip] than includegraphics* when using graphicx.)
However you can support all the argument parsing by hooking in the box after the arguments are parsed
