Testcase

The attached testcase was provided by Jacques Distler (from https://golem.ph.utexas.edu/wiki/instiki/show/Sandbox).

When you zoom in / out, the slash and 'D' elements are no longer displayed correctly. This is probably because we store two members m_ascent & m_contentRect on the renderer class and thy are not updated when zooming in / out. In general, in the past the solution for this kind of problem has been to get rid of these members. That's at least easy for m_ascent.
