Texture stores normalmap data swizzled in GGGR format. This is used for tangent space normal
maps. The R component is stored in alpha and G is stored in RGB. This packing can result in
higher quality when the texture data is compressed.

```ts
const TEXTURETYPE_SWIZZLEGGGR: "swizzleGGGR" = 'swizzleGGGR'
```
