fun onBuildCache(params: BuildDrawCacheParams): Unit

Callback invoked to re-build objects to be re-used across draw calls. This is useful to conditionally recreate objects only if the size of the drawing environment changes, or if state parameters that are inputs to objects change. This method is guaranteed to be called before DrawModifier.draw.

Parameters
`params: BuildDrawCacheParams`	The params to be used to build the cache.
