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