Detailed Description

An editor for inspection and modification of individual pixel values of a CanvasJavaImage.

The pixels of a CanvasHxImage can be inspected but not modified (at this moment ...).

The usage scenario is as follows: 1) the "user" (application) start a PixelEditor and calls updatePixels whenever a new location in a (new) image has to be displayed 2) when the user edits a pixel value in the table the pixel editor will update the CanvasImage and call _viewer.doRefresh
