FYI: A Gradient Strategy

Do you need to draw a large gradient area during window resizing? The slowness! Maybe an answer is to draw faster in poorer quality then when done sizing (i.e., Button Up), redraw in fine quality. The attached sample, if nothing else, is a good routine for drawing gradients between 2 colors. The extra code in the routines allows user-supplied quality values which when used with the example can show a dramatic decrease in the number of loop iterations required to draw in the different qualities/roughness.
