ShowingQuickAnnotations

Purpose

Set to True to signal chart that the quick draw annotations mechanism is being enabled. Quick Draw Annotations are annotations with GraphAnnotationTypes that are offset by 1 and negative  (+1)*(-1).  CacheBmp2 must be True.  See demo example 110 and it's related event code.

When ShowingQuickAnnotations is set True, only annotations with negative types are drawn, and drawn to a double buffered layer so the underlying chart view does not need updating. Thus allowing quick drawing and re-drawing of only the negative annotation types while the underlying chart screen is untouched. 

Only RenderEngine = Direct2D supports quick draw annotations.
