See https://docs.microsoft.com/en-us/windows/win32/api/d2d1effectauthor/nn-d2d1effectauthor-id2d1effectcontext

"Each call to ID2D1EffectImpl::Initialize will be provided a different ID2D1EffectContext interface. 
 This interface tracks resource allocations for the effect. When the effect is released, 
 the corresponding allocations will also be released."
