Collective on PetscDraw, but PetscDraw must be sequential

	draw	- the draw context
	m,n	- the global number of mesh points in the x and y directions
	xi,yi	- the locations of the global mesh points (optional, use NULL to indicate uniform spacing on [0,1])
	V	- the values

	-draw_x_shared_colormap	- Indicates use of private colormap
	-draw_contour_grid	- PetscDraws grid contour
