buffer
glInvalidateBufferData invalidates all of the content of the data store of a buffer object. After invalidation, the content of the buffer's data store becomes undefined.
GL_INVALID_VALUE is generated if buffer is not the name of an existing buffer object.
GL_INVALID_OPERATION is generated if any part of buffer is currently mapped.
