Quick question about SetPixel

[Arbiter]

Could someone please confirm the difference between SetPixel and SetPixelV.

I'm led to believe that SetPixelV is faster but the big question is - why?

[Mad Compie]

The SetPixel function sets the pixel at the specified coordinates to the specified color.

The SetPixelV function sets the pixel at the specified coordinates to the closest approximation of the specified color. The point must be in the clipping region and the visible part of the device surface.

Setpixels also returns the value of the pixel before it was set.

It returns the colour of the pixel being set (the 3rd argument)
