f0ab104f070bc7f569404826fea1828ed985638cvboxsync * to a user supplied callback function. This function will be called after
f0ab104f070bc7f569404826fea1828ed985638cvboxsync * any operation that modifies the framebuffer. The newly dirtied rectangles
f0ab104f070bc7f569404826fea1828ed985638cvboxsync * are passed to the callback.

f0ab104f070bc7f569404826fea1828ed985638cvboxsync * ShadowFBInit2 allows you to specify two callbacks, one to be called
f0ab104f070bc7f569404826fea1828ed985638cvboxsync * immediately before an operation that modifies the framebuffer, and another
f0ab104f070bc7f569404826fea1828ed985638cvboxsync * to be called immediately after.
