GTK: Fix autoc font size on GTK >= 3.21.0
GTK 3.21.0 fixed font size handling, leading to properly interpreting
pixels and points in CSS declarations. However, as older versions
incorrectly handled those, the code has to handle both behaviours.
From CSS, GTK < 3.21.0 actually applied the conversion to points, but
incorrectly: 10px was used as 10pt, but 10pt was scaled up twice.
So, assuming 96 DPI, it leads to:
font-size | 3.20.0 | 3.21.0 |
----------|---------|---------|
10px | 13.33px | 10px |
10pt | 17.77px | 13.33px |
So, we need to fix the code to accommodate for both (either scaling
ourselves, or adapting the unit: I chose the second, simpler, option).
