/**

* A JavaScript version of BufferedImage.

*

* Created from JSImagekit when creating an image

* from byte[] or from loading a GIF, PNG, or JPG image.

*

* The difference is that when from byte[] data, the

* field _pix will be initialized to the raster data,

* but _imgNode will be null; when an image is used, then

* _pix will be there, but it will not be populated unless

* a call to setRGB is made. Until then, JSGraphics2D.drawImage will

* simply use the image itself. But the _pix data will still

* be available as _imgNode.pbuf32.

*

* Only integer raster data RGB and ARGB have been implemented.

*

* useful states:

*

* _domNode != null ==> came from an image node (image file)

* _canvas != null ==> an image has been created from raster data

*

*
