ColorLegend and color maps

[John C. <jcu...@us...>]

Micha,

I noticed when using the custom color maps, that the legend does not get 
updated when changing colors. I believe this short patch solves this problem:

cvs diff qwt3d_plot.cpp

Try the Mesh2 example when changing to a different data set with a custom map.
