Description
This bug is for tracking the problem of slow rendering
on Mac OS X Tiger. The basic issue is summed up in the
following Apple java-developer links:

The short summary is that if you ever gain access to
the underlaying data array from a BufferedImage than all
Graphics2D calls to that BufferedImage will involve copying
the entire BufferedImage back and forth between main memory
and the GPU.
I will attach a patch (really a new file) that attempts to
work around this in the worst and most common case.
