[mapguide-internals] Correct legend display behaviour of swatches

Hi All,

In the process of fixing up ticket 2379, I noticed some strange behaviour in
how the legend in both the AJAX and Fusion viewers handle layers with both
composite and non-composite type styles.

It seems for such a layer, it will show the color swatches of all the types\
styles even though if a composite type style exists in a layer definition,
it should take precedence over the other feature type styles in that layer
definition (Is this correct? This is how the stylizer determines whether to
use basic or advanced stylization right?)

So going by that reasoning, if such a layer (having both composite /
non-composite styles) is shown on the legend in the AJAX/Fusion viewer, then
we should only be showing the swatches from the composite style and
disregard the other styles. Does this sound right?
