Title: Wrong resolution factor during LegendIcon creation with KEYIMAGE

MapServer 6.4.1.
I'm using the createLegendIcon class method with PHP Mapscript to generate a high resolution legend.
The RESOLUTION value in the mapfile is modified with php the script to obtain a 300 DPI legend icon.
Problem is, if the class has a KEYIMAGE defined, the symbol is scaled wrongly and zoomed way too much.
My solution is to modify maplegend.c at line 223, in function msDrawLegendIcon, and remove image_draw->resolutionfactor when theclass->keyimage != NULL:
msDrawMarkerSymbol(&map->symbolset,image_draw,&marker,&imgStyle,lp->scalefactor);
