When displaying a blob in gitweb, if it's an image, specify constraints for
maximum display width and height to prevent the image from overflowing the
frame of the enclosing page_body div.
This change assumes that it is more desirable to see the whole image without
scrolling (new behavior) than it is to see every pixel without zooming
(previous behavior).

I recently used Git to archive a set of scanned photos, and I used gitweb to provide access to them. Overall, everything worked well, but I found it undesirable that I had to zoom out in my browser on every photo to see the whole photo. In the spirit of making the default behavior the most likely correct behavior, this patch seems to be a good idea.
However, I'm not an expert on the use cases of gitweb. In order for the maximum size constraints to take effect, the image would have to be at least the size of the web browser window (minus a handful of pixels), so the affected images are usually going to be pretty big. Are there any common use cases for displaying a large image without scaling (and hence, with scrolling)?
Thanks,
Andrew
