I would definitely like to get my graphical menu stuff committed before you 
make such changes... :-)

Yes, but I haven't drastically changed the design of the core menu system 
except to add the concept of a "menu viewer" so that the text menu and 
graphical menu viewers can be treated uniformly at a higher level.

In fact, I am nearly ready to commit my graphical menu changes.  I was hoping 
to track down an apparent memory leak that shows up when switching themes many 
times in a row, but I don't have to let that prevent me from committing the 
current state of things.  I know Vladimir (phcoder) has done some work to get 
an SDL video driver working for grub-emu; I am hoping that I can somehow use 
memory debugging tools to track down my memory leak.

Does anyone have an idea if a tool like Valgrind would work with grub-emu to 
find the source of memory leaks?  I guess it should if grub-emu is using 
libc's malloc() and free() functions, right?
