OCR a screen capture - proof of concept code

This code will convert text in an image to editable text. The code must know the font used, so It will only work on screen captures - not on scanned images. I intend to add a screen capture function in the near future, so you can grab any text from any window. Right now this is just proof-of-concept code, and it has a few flaws.. :-) It doesn't work with Italic fonts or 'handwriting' fonts. I also need to find a way to get the routine find the vertical start of the text. Please comment on the general idea.
