KH GDI is a DLL written using C++ (tested with Borland C++ 4.52).
Its primary purpose is to wrap WIN API GDI calls, to hide the most
complex aspects of the vector drawing from the programmer.

You can perform the following tasks with KH GDI (only few basic 
    features listed):
1. Zoom your image or part of it:
    draw_pig();    // Your function
    zoom(2.5, 3.1) // Extend 2.5 times horizontally and 3.1 -
vertically
    draw_pig();    // Same function draws extended picture

2. Scroll your image or part of it:
    draw_pig();
    scroll(200, 200);  // All output after this command will 
                       // be scrolled
    draw_pig();        // Same function produces picture in the 
                       // different location

3. Mirror reflection.
    draw_pig();        // Your function
    mirror(100, 100);  // Vertical mirror, all output after this
                       // command will be reflected
    draw_pig();        // Draw reflected picture

4. Rotation and nested rotation:
    draw_pig();            // Your function
    rotate(alpha, x, y);   // All output after this command will be
                           // rotated alpha degrees relatively to
                           // point (x, y)
    draw_pig();            // Rotated picture
    rotate(beta, x1, y1);  // All output after this command will be 
                           // rotated (alpha, x, y) and then 
                           // (beta, x1, y1)  
    draw_pig();            // Image after complex rotation
    endrotate();           // End second rotation
    endrotate();           // End first rotation
