Even when the background _is_ a solid color, the icon artwork of GNOME
and friends is rendered with subpixel resolution: that means that for
border pixels, a non-integral amount of background shines through. If
the exact background is not known at the time an icon is made into a
graphics file, being restricted to transparency values of 0% and 100%
means that one either gets jagged edges or colored fringes around them
when displaying them.
For example, a blue icon rendered on red background will have border
pixels somewhere in the region between red and blue, depending on how
much of the background of a pixel gets covered. Display this
magentaish color on a green background, and you have a magenta tinge
between the blue and red areas.
