           Summary: ImageDocument 's incorrect zoom behavior.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED

        ReportedBy: kkimlabs at chromium.org


To reproduce the bug:
1. Visit an image e.g., https://www.webkit.org/images/icon-gold.png
2. Make the browser window(rendering area)'s height and width about 3 times bigger than the image.
3. Zoom in several times using keyboard shortcut (e.g., ctrl + '+' in Linux Chrome)
4. Zoom back to the original state (100%) using keyboard shortcut (e.g., ctrl + '-' in Linux Chrome)

Expected behavior:
The image size after Step 4. is identical to the image size at Step 1.

Observed behavior:
The image size after Step 4. is bigger than the image size at Step 1.


This is a bug in ImageDocument.cpp so it is reproducible on any browser and any platform.
