Four Colour Gradient - One colour on each corner - New Version

New Version! FOr those of you who did not see the previous project, this is a module that draws four colour gradients, one colour each corner of the rectangle. Thanks for voting for the previous release. Since RGB values range from 0 to 255, the changes of RGB values should fit in a square of dimensions 255 x 255. Hence using this theory, I have made a module that draws gradients super fast irrespective of it's size. Also, I have included optional halftoning of colours to get smoothest gradients irrespective of the screen resolutions (lower resolutions otherwise would cause 'banding'). Please vote. Thanks again.
