I know that also :-)

Well,

  pitch1 = ( width + 7 ) >> 3;

gives me

    width  pitch1
   ---------------
    1-8     1
    9-16    2
    ...

and

  pitch2 = ( ( width + 15 ) >> 4 ) << 1;

gives me

    width  pitch2
   ---------------
    1-16    2
    17-32   4
    ...

This is the intended result.  The values of pitch2 are even, and
pitch2 is always greater or equal pitch1; the allocated memory for
bitmap->buffer is thus always big enough.

What am I missing?  I couldn't find the place in ftraster.c where
`pitch' is used improperly or incorrectly.
