Re: ImageServer update projection problem

Hi Martijn,

Use ImageServer.createImage() instead. The getMapImage() stuff tried
to let the layers launch their swing workers, and track when they
finished, but that proves unreliable. The createImage() code uses the
ProjectionPainter interface that the Layer implements, and calls them
all serially.

The getMapImage() code is commented out in 4.5.3.
