122/**
123 * Common IFramebuffer implementation for all methods used by GUI to maintain
124 * the VM display video memory.
125 *
126 * Note that although this class can be called from multiple threads
127 * (in particular, the GUI thread and EMT) it doesn't protect access to every
128 * data field using its mutex lock. This is because all synchronization between
129 * the GUI and the EMT thread is supposed to be done using the
130 * IFramebuffer::NotifyUpdate() and IFramebuffer::RequestResize() methods
131 * (in particular, the \a aFinished parameter of these methods is responsible
132 * for the synchronization). These methods are always called on EMT and
133 * therefore always follow one another but never in parallel.
134 *
135 * Using this object's mutex lock (exposed also in IFramebuffer::Lock() and
136 * IFramebuffer::Unlock() implementations) usually makes sense only if some
137 * third-party thread (i.e. other than GUI or EMT) needs to make sure that
138 * *no* VM display update or resize event can occur while it is accessing
139 * IFramebuffer properties or the underlying display memory storage area.
140 *
141 * See IFramebuffer documentation for more info.
