GRID_DOT is the only type currently implemented, since the grid is drawn OVER the rendered canvas...
GRID_LINE would be a typical lined grid
GRID_CHECKER would be an alternating grey/light grey checker pattern (like Gimp)

GR_SPACE_X is the spacing between the vertical lines or dot columns
GR_SPACE_Y is the spacing between the horizontal lines or dot rows
GR_COLOUR GR_COLOR is the colour of the lines or dots, but ignored by GRID_CHECKER type
GR_TYPE is on of the GRID_* constants

There is currently only one type implemented and the way this works may change
as currently the grid is drawn last and it should probably be drawn first :-)
params is either a single integer for both the x and y spacing of the grid (ie for both)
or it is a sequence of {x,y} for an unequal horizontal and vertical spacing
supply 0 to params in order to suppress the drawing of the grid
gridtype is either GRID_DOT or one of the unimplemented types GRID_LINE or GRID_CHECKER see GRID_*
colour is the colour of the grid
