Thanks for the picture.
I still don't understand what it is you are having trouble
achieving. Here's what I understand so far:
* You called cairo_scale to make the text get larger
* The text got larger
* Something about the white box
I feel like there's a question in there, and I'd like to try to answer
it. But I'm still not sure what the question is. Can you help some
I can take some guesses as to what the question might be:
Question: How can I restrict the text to be clipped by a rectangle
the size of the white box?
Answer: Call the following before drawing the text:
cairo_rectangle (cr, x, y, width, height);
Question: How can I measure the size of the text so that I can
draw a rectangle that will bound it?
Answer: Use cairo_text_extents()
But I'm not sure that it's too productive for me to keep guessing
until I get to the right question. :-)

Good. That means that those functions or behaving exactly as intended.
