This fixes issue #2654. Usually get_text_width_height_descent is called as part of figure.draw, and then the graphics context is available to measure the text in. If get_text_width_height_descent is called as part of tight_layout instead of figure.draw, then no graphics context is available. But since we are only measuring text and not actually drawing anything, we can create a temporary bitmap context and measure the text there.
