Lightworks user effect Dx_Subtract.fx

This is an inverted non-additive mix. The incoming video is faded from white to
normal value at the 50% point, at which stage the outgoing video starts to fade
to white. The two images are then mixed by giving the source with the lowest
level the priority. The result is a subtractive effect.

Version 14 update 18 Feb 2017 by jwrl - added subcategory to effect header.

Cross platform compatibility check 5 August 2017 jwrl.
Explicitly defined samplers to fix cross platform default sampler state differences.
Swizzled two float variables to float4 to address the behavioural differences
between D3D and Cg compilers.

Update August 10 2017 by jwrl.
Renamed from SubtractDx.fx for consistency across the dissolve range.

Modified 9 April 2018 jwrl.
Added authorship and description information for GitHub, and reformatted the original
code to be consistent with other Lightworks user effects.
