Specifies the type of a GdkImage.
GDK_IMAGE_NORMAL
The original X image type, which is quite slow since the
image has to be transferred from the client to the server to display it.
GDK_IMAGE_SHARED
A faster image type, which uses shared memory to transfer
the image data between client and server. However this will only be available
if client and server are on the same machine and the shared memory extension
is supported by the server.
GDK_IMAGE_FASTEST
Specifies that GDK_IMAGE_SHARED should be tried first,
and if that fails then GDK_IMAGE_NORMAL will be used.
