R37:82a8db752ebc: Overview docker: fix shrinking the thumbnail to 1px
R37:9863e5e92d4a: Overview docker: fix shrinking the thumbnail to 1px
Summary

This fixes part of bug 390835: The thumbnail was shrinking to a width of 1 pixel and becoming increasingly blurry when resizing the overview window.

I've introduced an m_oldPixmap variable which stays constant over calls to resizeEvent, and m_pixmap is now set to a scaled version of this, rather than a scaled version of itself (which seemed to be the cause of the distortion.)

On each call to updateThumbnail m_oldPixmap is set to a copy of m_pixmap.
