{$IFDEF read_forward_definitions}
{ 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.
