   PetscDrawPointSetSize - Sets the point size for future draws.  The size is
   relative to the user coordinates of the window; 0.0 denotes the natural
   width, 1.0 denotes the entire viewport. 

   Not collective

   Input Parameters:
+  draw - the drawing context
-  width - the width in user coordinates

   Level: advanced

   Note: 
   Even a size of zero insures that a single pixel is colored.

   Concepts: point^drawing size
