<pre>It seems like for every character rendered the driver is copying the entire
window image back and forth, mipmapping and unmapping the entire window. Not at
all sure why it is necessary. But I understand the API is rather obsolete.
Really the the sensible destination for improvement effort would be freeglut,
no? I think GLUT is still a very widely used API.</pre>
