Lightworks user effect Dx_Optical.fx

This is an attempt to simulate the look of the classic film optical dissolve. To do
this it applies a non-linear curve to the transition, and at the centre mixes in a
stretched blend with a touch of black crush.

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.
Explicitly defined float4 variable to address the differing behaviours of the D3D
and Cg compilers.

Update August 10 2017 by jwrl.
Renamed from OpticalDx.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.
