As David Given pointed out, you can choose any vertical band of your image
this way (pass a pointer to the middle of a row, a width equal to the
band's width, and a rowstride to get to the middle of the next row). Also,
some rowstrides make GdkRGB faster IIRC; unfortunately I can't tell you
which ones those are. Ask Raph. :-)
