Typecast as bool the return value of cedrus_find_format in
cedrus_check_format as the return value of cedrus_check_format is always
treated like a boolean value.

Thanks for the patch! Could we also add !! to the returned pointer so that
we are sure that the function returns either false or true, but never a
non-zero value that is not true?

Cheers,
