cabde247f900dcf6e58d009bbdd15099c028c6fcvboxsync * the number of dirty rectangles, and a pointer to the first dirty rectangle
cabde247f900dcf6e58d009bbdd15099c028c6fcvboxsync * in the array.

cabde247f900dcf6e58d009bbdd15099c028c6fcvboxsync * ShadowFBInit initializes the shadowfb subsystem. refreshArea is a pointer
cabde247f900dcf6e58d009bbdd15099c028c6fcvboxsync * to a user supplied callback function. This function will be called after
cabde247f900dcf6e58d009bbdd15099c028c6fcvboxsync * any operation that modifies the framebuffer. The newly dirtied rectangles
cabde247f900dcf6e58d009bbdd15099c028c6fcvboxsync * are passed to the callback.
cabde247f900dcf6e58d009bbdd15099c028c6fcvboxsync * Returns FALSE in the event of an error.
cabde247f900dcf6e58d009bbdd15099c028c6fcvboxsync * ShadowFBInit2 is a more featureful refinement of the original shadowfb.
cabde247f900dcf6e58d009bbdd15099c028c6fcvboxsync * ShadowFBInit2 allows you to specify two callbacks, one to be called
cabde247f900dcf6e58d009bbdd15099c028c6fcvboxsync * immediately before an operation that modifies the framebuffer, and another
cabde247f900dcf6e58d009bbdd15099c028c6fcvboxsync * to be called immediately after.
cabde247f900dcf6e58d009bbdd15099c028c6fcvboxsync * Returns FALSE in the event of an error
