New VDP pixel info popup for tracing the source of pixel output

Description

A case has been identified from discussion with a user here:
http://gendev.spritesmind.net/forum/viewtopic.php?p=26168#26168
That it would be very useful for potentially many users to be able to quickly and easily determine information about the position and origin of any given pixel that is output by the VDP. We should implement a floating popup window to give detailed information about the origin of any given pixel on the screen, with all relevant data to track it back to the source data that generated it.
