Re: a GCC question

	I would guess that for smaller numbers of cases, GCC is deciding
that it is more efficient to use a series of "if" statements for a
decision tree instead of a switch statement.  You can explicitly code it
as such, e.g.,

if (bi->dispDeviceDepth == 32)
...
else if (bi-dispDeviceDepth == 16)
...
else if
...
else abort();

(BTW you do not provide a default case for some illegal value in your
switch statement.)
