A performance hint to the system to indicate that this Node should be cached as a bitmap. Rendering a bitmap representation of a node will be faster than rendering primitives in many cases, especially in the case of primitives with effects applied (such as a blur). However, it also increases memory usage. This hint indicates whether that trade-off (increased memory usage for increased performance) is worthwhile. Also note that on some platforms such as GPU accelerated platforms there is little benefit to caching Nodes as bitmaps when blurs and other effects are used since they are very fast to render on the GPU. The cacheHintProperty variable provides additional options for enabling more aggressive bitmap caching.

Caching may be disabled for any node that has a 3D transform on itself, any of its ancestors, or any of its descendants.

Returns: the hint to cache for this Node
