[udig-devel] A bit more for RenderingMetrics

[Jody Garnett <jgarnett@xxxxxxxxxxxxxxx>]

Hi Justin/Jesse and all those working on rendering these days.

Added "appearance" as a RenderingMetric - will replace canStyle as we 
switch over to the "Style Blackboard".

>     /**
>      * Percentle score for rendering appearance, 100 would be perfect.
>      * <p>
>      * Some quick guidelines:
>      * <ul>
>      * <li>Don't exceed 30% when using a "defaults" not provided by 
> the user
>      * <li>Perfectionists: Use a 100% to force the system (like with a 
> Scalebar)
>      * <li>Generalists: limit yourself to 90% when everything (in say 
> a SLD) matches
>      *     your abilities. (leave room for a perfectionist to step in)
>      * <li>Generalists: stay under 60% when you find content exists 
> you don't understand.
>      *     Imagine <i>FastLineStringRenderer</i> that checks for 
> LineSymbolizers,
>      *     a drop to below would be in order 60% if TextSymbolizers 
> that it cannot
>      *     handle are around. (But don't give up, maybe nobody handles 
> TextSymbolizers yet).
>      * <li>0% indicates utter and complete incompetence, basically 
> canStyle()==false
>      * </ul>
>      * </p>
>      *
>      * @return score in percent for style black board conformance.

And an update method allowing each rendering run to report back its 
results...
