Update gwenview to 1.2.0.  From maintainer Ian Zagorskih in PR pkg/29878

Compared to the latest stable release (1.0.1), this version includes...
too many things to list them all! Nevertheless, I would like to mention
a few important features (in no particular order):
  * Support for KIPI plugins, which brings you lots of fancy image
    manipulation possibilities.
  * Support for animated images.
  * Fast MMX-optimized image smoothing.
  * Asynchronous image loading, so the application do not look frozen
    while loading a big image.
  * Two KParts: one to display an image, another to browse folders.
  * Nifty On Screen Display toolbar.
  * Brightness, contrast and gamma adjustment.
