[orca-list] OCR Current Window

[chrys87 <chrys87 web de>]

Hi Guys,
i play a little arround with tesserwrap. i dont know if it really make 
sense but maybe someone need this.
i wrote a little orca-cust for taking a screen shot of the current 
window and pass it through tesseract. just press
orca + m
orca will start reading the content of the window (maybe the image 
program or browser with pictures or an other not accessible content) and 
set it to the clipboard.
You need tesseract tesserwrap, your tesseract-language-pack and orca >= 3.14

hier is the cust script for those who are interested in:
