The pixbuf-demo gets its own subdirectory, the other small
tests move from demos/ to tests/.

The ownership of the return value for gdk_pixbuf_get_from_window() and
gdk_pixbuf_get_from_surface() was determined by the first argument.

Because that is an ugly design and the functions are new to GTK3, we
decided to adapt them.
And that adaptation was quite easy since almost no one passses anything
but NULL as the first argument.

The Colormap argument needed to be removed, so the renaming is just a
side effect.

Use G_GSIZE_FORMAT instead of %i

The warning was added in
commit ba651d40

This patch adds an icc-profile option to a GdkPixbuf which can
be used to read or write an embedded ICC profile.

Add PNG support for now, but other image formats are awaiting
review.
