glInvalidateTexSubImage invalidates all of a texture image. texture and level indicated which texture image is being invalidated. After this command, data in the texture image has undefined values.
level must be greater than or equal to zero and be less than the base 2 logarithm of the maximum texture width, height, or depth.
GL_INVALID_VALUE is generated if level is less than zero or if it is greater or equal to the base 2 logarithm of the maximum texture width, height, or depth.
GL_INVALID_VALUE is generated if the target of texture is any of GL_TEXTURE_RECTANGLE, GL_TEXTURE_BUFFER, GL_TEXTURE_2D_MULTISAMPLE, or GL_TEXTURE_2D_MULTISAMPLE_ARRAY and level is not zero.
