/* 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.
