In OpenGL this is called the (base) internal format which is an expectation expressed by the client for the minimum supported texel storage format in the GPU for textures. Since we store everything as RGBA in a `FloatVector4`, the only thing we do in this patch is remember the expected internal format, and when we write new texels we fixate the value for the alpha channel to 1 for two formats that require it. `PixelConverter` has learned how to transform pixels during transfer to support this.
