Zooming the canvas messes up text

[Aditya Rajgarhia <adityar7 gmail com>]

Hi,

I have noticed, both in my application as well as in the demos 
distributed with GooCanvas, that zooming the canvas using set_scale() 
can cause issues with any text on the canvas.

As the canvas is zoomed increasingly, some of the letters within a text 
widget do not scale properly, and begin to overlap with each other. You 
can see this in the examples/text demo application (by scaling the text 
a few times), or in the following screenshot from my application:

Has anyone come across this issue before? Unless I'm doing something 
wrong, this is quite a bug.

Thanks,

Aditya
