SVN commit 511560 by cgilles:

digikam from trunk : new "Zoom Factor" option for control panel dialog used in image editor plugins. 

Current zoom factor are x1.0, x 1.5, x2.0, x2.5, x3.0. For any memory performance reasons about to store image data in memory (actually uncompressed), i have limited to 3.0 the max zoom factor. This is enought normally...

Before, Control Pannel dialog always displayed the image in x1.0. Now, you can see zoom into the image all fine details like JPEG artifacts or singular points (hot pixels for example) to correct using image editor tools.

Here we are a screenshot of "Restoration" plugin to correct JPEG artifact using x2.5 zoom factor :

This commit fix any parts of the old implementation to optimize memory using by the preview image data, especially with 16 bits images. Any small bugs have been fixed about seperate view mode rules.
