f78b12e570284aa8291f4ca1add24937fd107403vboxsync * the number of dirty rectangles, and a pointer to the first dirty rectangle

f78b12e570284aa8291f4ca1add24937fd107403vboxsync * ShadowFBInit initializes the shadowfb subsystem. refreshArea is a pointer
f78b12e570284aa8291f4ca1add24937fd107403vboxsync * to a user supplied callback function. This function will be called after
f78b12e570284aa8291f4ca1add24937fd107403vboxsync * any operation that modifies the framebuffer. The newly dirtied rectangles
f78b12e570284aa8291f4ca1add24937fd107403vboxsync * are passed to the callback.
f78b12e570284aa8291f4ca1add24937fd107403vboxsync * Returns FALSE in the event of an error.
f78b12e570284aa8291f4ca1add24937fd107403vboxsync * ShadowFBInit2 is a more featureful refinement of the original shadowfb.
f78b12e570284aa8291f4ca1add24937fd107403vboxsync * ShadowFBInit2 allows you to specify two callbacks, one to be called
f78b12e570284aa8291f4ca1add24937fd107403vboxsync * immediately before an operation that modifies the framebuffer, and another
f78b12e570284aa8291f4ca1add24937fd107403vboxsync * to be called immediately after.
f78b12e570284aa8291f4ca1add24937fd107403vboxsync * Returns FALSE in the event of an error
