-/*  image.c
- *  This program demonstrates drawing pixels and shows the effect
- *  of glDrawPixels(), glCopyPixels(), and glPixelZoom().
- *  Interaction: moving the mouse while pressing the mouse button
- *  will copy the image in the lower-left corner of the window
- *  to the mouse position, using the current pixel zoom factors.
- *  There is no attempt to prevent you from drawing over the original
- *  image.  If you press the 'r' key, the original image and zoom
- *  factors are reset.  If you press the 'z' or 'Z' keys, you change
- *  the zoom factors.
