/// This method does not update the size of the current bitmap. If the contents of the source bitmap do not fit in the current bitmap, this method fails. Also, note that this method does not perform format conversion; the two bitmap formats should match. Passing this method invalid input, such as an invalid destination rectangle, can produce unpredictable results, such as a distorted image or device failure. Calling this method may cause the current batch to flush if the bitmap is active in the batch. If the batch that was flushed does not complete successfully, this method fails. However, this method does not clear the error state of the render target on which the batch was flushed. The failing <see cref="int"/> and tag state will be returned at the next call to {{EndDraw}} or {{Flush}}.
