app, devel-docs: improve position of loading text on splash image.

The upper text will be centered on the top quarter of the bottom quarter
of the splash image, whereas the bottom text will be centered on the
bottom quarter of the bottom quarter of the splash (unless the splash is
too small, in which case the double of the layout pixel extents will be
used). Basically don't use absolute pixel values anymore for
positionning. This should all be done relatively since there are
nowadays all kind of display size (and positionning the text 6 pixels to
the bottom, as it was done, may be ok on low density displays, yet will
look ugly on high density screens).

Also write this down in the splash requirements in the release howto so
that splash designers are aware that the bottom quarter of their image
will have to be adapted for printing text.
