PATCH: Graphincal explain integrated in sql editor - Mailing list pgadmin-hackers

PFA the first patch for graphical explain integrated in sql editor.

Below are the few things which are different from previous patch which was sent for stand alone graphical explain.

 -  Now user can select Explain/Explain Analyze with four optional properties (Verbose, costs, timing and buffers)

 - Initially graph will be scale (according to only its width not height) to fit to screen so no blank space will be there in case of very large graph.

- Along with zoom in/out button, "zoom to original" button is also provided, by clicking on which graph will be scale to its original size (not same as initial one which is according to screen size).

Please do review this patch and let me know in case you have any comments.
