    Make gdk_visual_get_*_pixel_details work again
    
    These functions are supposed to return the numbers of consecutive
    1 bits in each components mask as precision. However, due to a
    copy-paste mistake when this code was moved around in
    commit 70d689cddda0dc616af97e8ed047d0c0acf7c7a6, the precision
    was always reported as zero. This affects only a few applications
    that directly set window background on X11 windows, such as emacs.
