When clipping CDATA for icons take data from center of image (bug #58144).
* QtHandlesUtils.cc (makeImageFromCData): Rename x_off, yoff to x_img_off,
y_img_off. Add new variables x_cdat_off, y_cdat_off. When there is a size
mismatch between the source CDATA and the destination QImage, take data from
center of CDATA by using x_cdat_off, y_cdat_off offsets and place in center of
QImage by using x_img_off, y_img_off.
