289/**
290 * Common IFramebuffer implementation for all methods used by GUI to maintain
291 * the VM display video memory.
292 *
293 * Note that although this class can be called from multiple threads
294 * (in particular, the GUI thread and EMT) it doesn't protect access to every
295 * data field using its mutex lock. This is because all synchronization between
296 * the GUI and the EMT thread is supposed to be done using the
297 * IFramebuffer::NotifyUpdate() and IFramebuffer::RequestResize() methods
298 * (in particular, the \a aFinished parameter of these methods is responsible
299 * for the synchronization). These methods are always called on EMT and
300 * therefore always follow one another but never in parallel.
301 *
302 * Using this object's mutex lock (exposed also in IFramebuffer::Lock() and
303 * IFramebuffer::Unlock() implementations) usually makes sense only if some
304 * third-party thread (i.e. other than GUI or EMT) needs to make sure that
305 * *no* VM display update or resize event can occur while it is accessing
306 * IFramebuffer properties or the underlying display memory storage area.
307 *
308 * See IFramebuffer documentation for more info.
