public boolean lockResources(PresentableState pState) Locks any underlying resources needed for a createGraphics/prepare/present sequence and returns a boolean indicating if the presentable needs to be recreated. If the method returns true and the Presentable implements `GraphicsResource` then its `dispose()` method will be called prior to recreating a new `Presentable` object and so no resource should need to be locked in that case. The resources will be unlocked in either `prepare()` or `present()`. Parameters pState:PresentableState The presentation state for the upcoming pulse Returns:boolean true if the caller should recreate the Presentable

public boolean lockResources(PresentableState pState)

Locks any underlying resources needed for a createGraphics/prepare/present sequence and returns a boolean indicating if the presentable needs to be recreated.
