auto hasLoaded() const -> bool: Returns true if the texture has been correctly loaded.
auto width() const -> int: Returns texture width.
auto height() const -> int: Returns texture height.
auto size() const -> Vector2i: Returns texture size as a Vector2<int> class.
auto mipMapCount() const -> int: Returns the number of MIP maps stored in the texture file.
auto dataSize() const -> unsigned long: Returns texture data size in bytes.
auto dataSize(unsigned int mipMapLevel) const -> long: Returns the texture data size in bytes for the specified MIP map level.
auto texFormat() const -> const TextureFormat&: Returns the texture format object.
auto pixels() const -> const GLubyte*: Returns the pointer to pixel data.
auto pixels(unsigned int mipMapLevel) const -> const GLubyte*: Returns the pointer to pixel data for the specified MIP map level.

void loadPixels(GLenum internalFormat): Loads pixel data from a texture file holding either compressed or uncompressed data.
void loadPixels(GLenum internalFormat, GLenum type): Loads pixel data from a texture file holding either compressed or uncompressed data, overriding pixel type.

bool hasLoaded_: A flag indicating if the loading process has been successful.
std::unique_ptr<Death::IO::Stream> fileHandle_: Texture file handle.
