Fix bug of clearing COF_TEMP_MARK.

draw_shapes_in_dirty_areas() mark COF_TEMP_MARK on coords and clear
them before leaving.  But, it always clear the same one coord for
several times and keep others untouched.  It is a logical error.  It
can be avoided by avoiding to use the variable at mutliple place for
different purpose in a function, and compiler will check it out by
yelling that the variable is used before assigning a value.
