	)

OSDL's version of putPixelAlpha.

Parameters:

	color	this color is not a color definition, it is a pixel color already converted to the pixel format of the target surface.
	the	full precision alpha coordinate of the pixel to put.

The greater the 'alpha' parameter is, the closer to the alpha of put pixel the alpha of the final pixel will be (for a null 'alpha', final pixel alpha will not be modified, for a maximum 'alpha' the alpha of the resulting pixel will be the alpha of put pixel.

Note:

the alpha color element has to be specified, since it cannot reliably be deduced from the 'color' parameter, which is already encoded to a specific pixel format.
