LyX needs help: Broken font metrics computation

[Michael Schmitt]

Jean-Marc,

> Michael, a quick question: are you sure of your test program?

No, I am not sure. I just tried to create the smallest possible test case 
that does not crash and produces some "reasonable" output. To make sure we 
are not hunting a phantom, we can use the Qt example "examples/drawdemo/" 
and inject the code of the test case.
