The size of a mip map is `max{floor(width / 2 ^ level), 1} x max{floor(height / 2 ^ level), 1}`,
where `width x height` is the size of the full-resolution image,
`level` is the integer mip map level
and the smallest mip map has `1 x 1` resolution.
If `regenerateMipMapLevels` is called with custom mip map data,
the mip map sizes are calculated in this function and separately in `uploadTexture`.
`uploadTexture` calculates a size by `floor(width / 2 ^ level) x floor(height / 2 ^ level)`.
To support non-square textures, after this change,
`uploadTexture` sets the mip map width or height to `1` if it is `0`.
