The last arguments are optional, for example if the * function is not using mask, then 'mask' and 'mask_stride' can be * omitted when doing a function call. * * Arguments 'src' and 'mask' contain either a pointer to the top left * pixel of the composited rectangle or a pixel color value depending * on the function type.
