#fetch(coord : IVec2, lod : Int32 = 0) : Vec4
Fetches texel at integer pixel coordinates without bilinear filtering.
#sample(uv : Vec2) : Vec4
Samples the texture at normalized coordinates uv, returning an RGBA vector.
#sample_lod(uv : Vec2, lod : Float32) : Vec4
Samples the texture at explicit mipmap level of detail lod.
#size(lod : Int32 = 0) : IVec2
Returns dimensions of the texture at mipmap level lod as ivec2(width, height).
