Documentation : Typo in "Interpreting Deep Pixels"

[danieldresser-ie]

In the document "Interpreting Deep Pixels", viewable both here:
https://github.com/AcademySoftwareFoundation/openexr/blob/master/OpenEXR/doc/InterpretingDeepPixels.pdf
and here:
https://www.openexr.com/documentation/InterpretingDeepPixels.pdf

in the equations at the top of page 11, when defining S_i,new(c) when both source alphas are <1, I'm pretty confident that the division by "w" should instead be a multiply.

Instead of:
( S_i( c ) * v_i + S_j( c ) * v_j ) / w
It should read:
( S_i( c ) * v_i + S_j( c ) * v_j ) * w

I think this must be a typo, based on comparing it to both the code for mergeOverlappingSamples at the end of the document, which uses a multiply, and also comparing to Peter Hillman's "Theory of Deep Pixels".

After referencing this document pretty frequently, but always just going to the code at the end, I think I finally understand why this page always confused me. This does seem to be one of the most useful and authoritative sources on how to work with deep images, so it would probably be worth fixing.
