Highlight features behavior change suggestion

[kafka@…]

In 4.0.1 the highlight color is applied only for last style in a class. It is 
good for points or lines but for polygons last style may be usually outline. I 
suggest to change this to FIRST style (usually polygon fill). Also my 
suggestion is to enable highlight "transparent" (-1 -1 -1) coloured fills to 
see only highlighted fills (see attached image). There may be many combinations 
e.g. highlight all classes etc. (I have it implemented too), but this way is 
the simplest and usefull.

The changed source code is attached

Thank you

Actually I was thinking of ditching query map style altogether. Instead I would 
advocate adding to the class STYLE section. The idea would be that you could 
define special STYLES that would be applied only when drawing a query result 
set. If no query STYLES are defined then you would use the existing STYLES. 
This way you could have total control of how you present matching features- 
e.g. some yellow, some red and so on. What do you think?

It is very good idea. Only one small disadvantage is need of more code rows in 
map file. Maybe layers with no highlight style definition would inherit the map-
level querymap settings. What do you think?

Let's put this one off until 4.3/4.4 (early June).

Marking as won't fix as we'll tackle QUERYMAPs in a future release and create a new ticket surrounding the associated RFC...
