+/**
+ * Provides extended BufferStrategy capabilities, allowing to specify
+ * the type of vertical refresh synchronization for a buffer strategy.
+ *
+ * This BS capability is always page flipping because v-sync is only relevant
+ * to flipping buffer strategies.
+ *
+ * Note that asking for a v-synced BS doesn't necessarily guarantee that it will
+ * be v-synced since the vsync capability may be disabled in the driver, or
+ * there may be other restriction (like a number of v-synced buffer strategies
+ * allowed per vm). Because of this {@code createBufferStrategy} doesn't
+ * throw {@code AWTException} when a v-synced BS could not be created when
+ * requested.
