I've been investigating some font rendering issues in Bitwig Studio.
While trying to reproduce a test case where showing the string "222" would
clip the 2 by one pixel on the top, and showing "222h" would not because
the h is higher and I believe that the text extents were used somewhere...
Anyway I've found something even worse on the way: ANTIALIAS_BEST renders
totally unreadable text in some conditions where the other anti aliasing
algorithms are working.
>From the bugzilla, this issue seems to be known for at least one year:
I've attached a test case to it, so it will be very easy for you to
reproduce the bug and fix it.
