b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * User defined callback function. Passed a pointer to the ScrnInfo struct,
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * the number of dirty rectangles, and a pointer to the first dirty rectangle
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * in the array.

b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * ShadowFBInit initializes the shadowfb subsystem. refreshArea is a pointer
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * to a user supplied callback function. This function will be called after
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * any operation that modifies the framebuffer. The newly dirtied rectangles
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * are passed to the callback.
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * Returns FALSE in the event of an error.
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * ShadowFBInit2 is a more featureful refinement of the original shadowfb.
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * ShadowFBInit2 allows you to specify two callbacks, one to be called
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * immediately before an operation that modifies the framebuffer, and another
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * to be called immediately after.
b8e299dddd091ae24e0c08c45d91b8f937bd14d2vboxsync * Returns FALSE in the event of an error
