This function sets the PROP_CLEAR_COLOUR property to the color defined by the paramters. Since PROP_CLEAR_COLOUR stores the colour as a single 32-bit number, it is useful to have this function to update the colour using 0-255 channel values. The default value for this is 0, which is transparent. This is the color value used by clearBuffer when clearing the pixel buffer.
