STATE_polygon_is_uniform_brightness

 

 


   return YES or NO
   light intensity values are used with bitmap filled polygons
   instead of using several bitmaps in different 
   brightness levels we can simply use this function
   we can also specify a different brightness value for each point
   of the polygon (using the POINT API functions)
   In that case the rendering of the polygon will be slower
   if all the points have the same brightness the rendering time
   is not damaged.
   relevant only for bitmap fill

   STATE_polygon_get_brightness()
