Description Mike Wyrzykowski 2023-05-12 10:45:19 PDT 
WGSL support for texture_external: https://gpuweb.github.io/gpuweb/wgsl/#external-texture-type

In order to support this, use of "texture_external nameForT" will likely need to generate the following information in the argument buffer at a minimum:

texture2d<half> nameForT_FirstPlane;
texture2d<half> nameForT_SecondPlane;
float3x3 nameForT_UVRemapMatrix;
float4x3 nameForT_ColorSpaceConversionMatrix;


texture_external can only be used with textureLoad or textureSampleBaseClampToEdge. I will write up separate issues for those.
