/* 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.
