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).

GTK 3.20 doesn't seem to like it so much when looking up details of a
non-exact current style context state, so use the current one.
This is GTK being really picky as in this case we are just missing the
`DIR_LTR` flag, which we definitely don't care about, but let's make it
happy.

GTK 3.20's GtkScrolledWinodw doesn't like having a too small allocation
and spews scary assertion failures. Fix that by requesting the real
size we'd like instead of hard-coding 1 as small-enough value in our
overriding height requisition method.
The actual value doesn't really matter so long as it's small enough
anyway, as we resize the popup to fit later on.
Note: this moves the actual implementation of ListBoxX::GetRowHeight()
to the new convenience function treeViewGetRowHeight(), with no changes
in implementation.

GTK 3.20 introduced a sub-node named "border" to the frame, requiring
to lookup the border on that sub-node rather than on the frame itself.
Unfortunately supporting this requires to be built against GTK 3.20, as
it requires API this version introduced. This means that a build
against an older version won't be able to get the popup sizing right if
running on 3.20. To mitigate this, add reasonable fallback defaults
when running 3.20 but built on an earlier version, to try and avoid

2px-scrolling on GTK 3.20's default theme.
Now the popup is cached the row height has to be re-computed when the
font changes on GTK2 too.
Mostly closes#702.

GtkScrolledWindow in GTK 3.16 might have a minimum and natural height
of 0 if GTK_OVERLAY_SCROLLING is enabled (which is the default), so we
need to fix our overridden minimal height to never be greater than the
natural height.
Do that by only changing the minimal height if it is greater than what
we want.
I don't know why we didn't use to set 0 here, but it might be that a
height of 0 caused problems on older GTK versions, so keep 1 to be sure.

This fixes drawing on a surface that has different settings (like
scaling) than the display surface, by performing the measurements on a
layout properly set up for the target surface.
In practice, this fixes e.g. printing on a scaled surface.

Always get the Pango context through GTK+ API rather than creating it
from a Cairo context to always get a context set up for the screen.
This fixes font size issues when using Cairo rendering.

Keep Scintilla's directory structure mostly and only remove unused lexers.
For now, this will break the build. The build systems have to be updated as well as scintilla_changes.patch.
