@c@C1@b@_ Raster Scale

     Scale an image by arbitrary scale factors or to fit it into a 
     pre-determined size.

@b Options

@f  Scale Factors
     Scale factors in X- and Y-directions can be adjusted individually (if
     aspect ratio is not to be kept) or simultaneously (keeping the aspect
     ratio) by pressing the mouse on the arrow buttons.

@f  Reporting
     The current scaling request can either be reported as scaling
     factors (current size/original size) or as the resulting size
     in pixels. You can choose the reporting method by toggling the
     ShowSize and ShowScale buttons.

@f  Anti-aliasing
     By default, subpixel sampling is enabled and therefore, the resulting
     image will be in RGB format. If exact number of colors are to be
     kept, anti-aliasing can be turned off by toggling this flag.

     For Scale factors greater than 0.5, a simple pixel blending can be used 
     for subpixel sampling without causing too much error but much faster.
     General box sampling is enabled by clicking the mouse on Hi-Fi button.

@f Fitting the image into a fixed size
     To enable this feature, press the Exact button. You can adjust scaling
     factor independently. In actual scaling, the smaller of the two
     factors is used and aspect ratio is preserved by filling the 
     other direction with a solid color, which can be set by pressing
     FillCol button.
