Yes, there still were a few uses of #<< and #>> still laying around in
JPEGReadWriter; I've cleaned them up in this changeSet which improves
performance by about 4%.
Unfortunately, the Interval>>to:by:do: use that you point out in
JPEGReadWriter>>idctBlockInt:component:
is there because that method is on the edge of not compiling -- the
required frame size is close to exceeding the maximum of 32 for a large
frame. Changing it to use the compiler in-lined to:by:do: increases the
requirements to over that limit.
