BlitFadeRaster(<-x <-y <-list <-width <-startAlpha <-endAlpha <-time)

Blits a list of colors to the raster. The list will be treated as a flattened array mapping to a rectangular 'sprite' that is 'width' wide. The blit will happen at the specified location in the raster and the bottom left of the sprite will start at that location. The startAlpha, endAlpha, and time control how the fade out will occur. Unlike BlitRaster, this routine will continue to draw into the raster each from for 'time' frames. The color of each pixel in the list will have its alpha value tweened between startAlpha and endAlpha over time.
