+/* Types of images.
+ *   Normal: Normal X image type. These are slow as they involve passing
+ *	     the entire image through the X connection each time a draw
+ *	     request is required. On Win32, a bitmap.
+ *   Shared: Shared memory X image type. These are fast as the X server
+ *	     and the program actually use the same piece of memory. They
+ *	     should be used with care though as there is the possibility
+ *	     for both the X server and the program to be reading/writing
+ *	     the image simultaneously and producing undesired results.
+ *	     On Win32, also a bitmap.
+ *   Shared Pixmap: Also a shared memory image, which also has a
+ *	     pixmap using the same memory. Used by gdk_imlib with the
+ *	     Win32 backend.
