*Texture3dMipmap and *Texture1dMipmap do not have the write method

[McArdellje]

Non-2d texture mipmaps lack a method similar to write for the 2D mip maps that runs the respective glTexSubImage*D methods on them (the ones on the 2D textures map to glTexSubImage2D internally).
The 1D and 3D mipmaps should also have a similar method mapping to glTexSubImage1D and glTexSubImage3D respectively.
Without this you have to use raw_upload_from_pixel_buffer which requires uploading the data to the GPU and then copying it into the texture, which is obviously going to be slower than copying the data directly into the texture.
