       libAfterImage/transform/scale_asimage()

       This  function  will  try  to  convert double precision indexed image data into actuall color image using
       palette. Original data should be attached to ASImage using vector member. Operation  is  relatively  fast
       and allows representation of scientific data as color image with dynamically changing palette.

       asv    - pointer to valid ASVisual structure

       src    - source ASImage.

       slice_x_start
              - ending of the left corners

       slice_x_end
              - beginning of the right corners

       slice_y_start
              - ending of the top corners

       slice_y_end
              - beginning of the bottom corners

       to_width
              - width of the generated image;

       to_height
              - height of the generated image;

       scaled - if True - middle part of the image will be scaled, otherwise - tiled;

       out_format
              -  optionally describes alternative ASImage format that should be produced as the result - XImage,
              ARGB32, etc.;

       compression_out-
              compression level of resulting image in range 0-100;

       quality
              - output quality.

       - adjusts image color properties in HSV colorspace

       Performs Gaussian blurr of the image ( useful for drop shadows and the likes ).

       creates ASImage from double precision indexed image data - useful for scientific visualisation.

       -  convenience  function  allowing  one  to create new ASImage, set its vector data and colorize it using
       palette - all in one step.

       - Fills rectangle within the existing ASImage with specified color.

       - rotates ASImage in 90 degree increments

       - renders linear gradient into new ASImage

       enlarges ASImage, padding it with specified color on each side in accordance with requested geometry.

       - scales source ASImage into new image of requested dimensions.

       - slice ASImage leaving its corners intact, and scaling the middle part.

       - tiles/crops ASImage to desired size, while optionally tinting it at the same time.

       New ASImage  on success, NULL on failure.
