Avoid accidentally scaling the tab bar when using IncreaseFontSize.
Use a "better" default title font based on the platform.
Avoid a gap between bottom of tab button and dividing line at
certain font sizes.
When split horizontally, selecting multiple lines at the top of the left
pane could paint a horizontal selection line all the way across the rest
of the terminal to the right hand edge.
Removes the dependency on knowing where the pane top/left position
is so that the line render routine could be used in more places.
Adjusts the tab bar and scroll bar positioning so that the tab bar
ignores window padding and is always flush with the top/bottom window
edge (full width as well), and that the scroll bar top/bottom respects
the tab bar position and height.
More of a "fix"; we use some heuristics based on the bearing
and glyph width to figure out if a sequence looks like a funky
ligature that moves left to render the glyph.
This may be prone to false positives, but the consequences are low:
when we think a glyph is part of a ligature, then rather than using
the cursor_fg color (which is typically black, or close to invisible),
we retain the normal text fg color.
This way the portion of the glyph outside of the cursor retains its
foreground color, and just the cell containing the cursor may have
a slightly funky fg color in the case where the heuristic was bad.

`use_fancy_tab_bar` switches to an alternate rendering of the tab
bar that uses the window_frame config to get a proportional
title font to use to render tabs, as well as rendering a few
additional elements to space out and make the tabs feel more
like tabs.
Computing the number of tabs doesn't respect the alternate font
at this time.
Formatted tab item foreground and background colors are also
not respected at this time.

The description of Nop was incorrect; it was describing
DisableDefaultAssignment. Just make this bit use the same
example from DisableDefaultAssignment's docs.
We now compute the cap-height from the rasterized glyph data.
Moved the scaling action of use_cap_height_to_scale_fallback_fonts from
glyphcache into the font resolver: when enabled, and we have data
about the baseline font and the font being resolved, then the resolving
font will be scaled such that the cap-height of both fonts has the same
pixel size.
The effect of this is that `I` glyphs from both fonts should appear to
have the same height.
Added a row of `I`'s in differing styles at the bottom of styles.txt
to make this easier to visualize.

This is to handle situations such as some versions of the Terminus
bitmap font, where the individual bitmap strike sizes are broken
out across multiple individual files.
Font matching now passes down the nominal pixel height based on
the current DPI and font scale factor, and will use that to select
the font file that has the closest pixel size.
Previously, it would be potentially undefined which of the Terminus
font files would be selected.
