Legend graphics for layer of type annotation

[szekerest]

It would be desirable to reflect some of the attributes of the annotation 
layers like font and text color in the map legend. The legend image could be 
drawn as a sample text with the corresponding font and color. The following 
code snippet can do the work like this:

maplegend.c line 128

switch(type) {
    case MS_LAYER_ANNOTATION:
	  if (class->label.size != -1)
	  {
		  rectObj label_rect;
		  labelObj label = class->label;
		  label.angle = 0;
		  if (label.type == MS_TRUETYPE) label.size = height;
		  marker.x = dstX + MS_NINT(width / 2.0);
		  marker.y = dstY + MS_NINT(height / 2.0);
		  if(msGetLabelSize("Abc", &label, &label_rect, &map->fontset, 
1.0) != -1)
		  {
			  pointObj label_point = get_metrics(&marker, MS_CC, 
label_rect, 0, 0, label.angle, 0, NULL);
			  msDrawTextGD(img, label_point, "Abc", &label, &map-
>fontset, 1.0);
		  }
	  }

The sample text might also be placed in the map file.

A neat idea, but too big an addition to 4.8. Marking for 4.10...

Too late (or too lazy) for 5.0 (unless you want to take it Tamas). Moving to 5.2.
