Show a basic storage type to handle a simple RGB raster graphics image,
and some primitive associated functions.

If possible provide a function to allocate an uninitialised image,
given its width and height, and provide 3 additional functions:

   one to fill an image with a plain RGB color,
   one to set a given pixel with a color,
   one to get the color of a pixel.


(If there are specificities about the storage or the allocation, explain those.)

These functions are used as a base for the articles in the category raster graphics operations, 
and a basic output function to check the results
is available in the article write ppm file.




function main() {
  Var:Number shape;
 
  Image:New(50, 50, shape)
  Draw:RectFill(0, 0, 50, 50, 0xFF0000, shape)  //one to fill an image with a plain RED color
 
  Draw:Pixel(30, 30, 0x0000FF, shape)           //set a given pixel at (30,30) with a BLUE color
 
  while (B1 == false) {
    Image:Blit(10, 10, shape, screen)
    Screen:Render()
  }
}
