screenshot application does only scale on width
the screenshot application currently scales the pictures to one of the three given sizes (640 x 480 ; 800 x 600 ; 1024 x 768). If a picture is not in 4:3 format, it does only care about the width of a picture. This leads to hugh scaled pictures, if only parts of a screen are used (like the stock menu that has ~ a 3:7 format).
Because of that I suggest to:
1) Add a link "real size" - should be the default one
2) Change the code, that it scales the picture that way, that x an y are used for scaled size calculation (so in case of the stock menu it should see, that the important size is the y size and not the x size.
