39 * Normal: Normal X image type. These are slow as they involve passing
40 * the entire image through the X connection each time a draw
41 * request is required. On Win32, a bitmap.
42 * Shared: Shared memory X image type. These are fast as the X server
43 * and the program actually use the same piece of memory. They
44 * should be used with care though as there is the possibility
45 * for both the X server and the program to be reading/writing
46 * the image simultaneously and producing undesired results.
47 * On Win32, also a bitmap.
