In Python, I Need a script that given a windows button control (hwnd)
it retrieves the pixel data of the image displayed on the button
(without taking a screenshot)  it should be able to grab the button
image data while the window is minimized.  For example in the game
freecell that comes with windows, each card is a button, so while the
window is minimized the script should be able to identify the
imagedata of all shown cards.
