Uploads size bytes of pixel data into mip level 0 of this texture.

The source data is laid out at pixelsPerRow pixels (texels) per row, so callers can pass strided data (e.g. an SDL_Surface with row padding) without first tightening it. The texture's dimensions and layer count come from its metadata, so this must be called after initWithDevice has populated them.
