Curly underlines are implemented by drawing two parallel, complementary-dashed
lines with a distance of 2 pixels.
This means they dont' scale with font size. They only look good with a small
font size. At a first glance, they are also not so easy to tell apart from
regular underlines.
Fix this by
1. drawing a cosine wave instead of of parallel dashed lines
2. always drawing a full wave period per glph, indendent of the font size
3. using the text line width, instead of always using 1px
A similar (but much less prominent) issue exists for double underlines.
Change them too, keeping the implementation consistent.
Tested with
printf '\033[31m\033[4:3mcurly\033[4m\033[31m\033[4:2mdouble\033[4m'
Note that the curly underline overlaps with the "y". Perhaps we should
fix this.
Probably there are more improvements to be made, and it's possible there is
a more elegant solution than repeated drawArc() calls.
Publishing this early nevertheless because it's hopefully close to an overall
improvement; But I did not have a chance to look into the bugs mentioned in

Konsole - KDE's Terminal Emulator
Konsole is a terminal program for KDE.
As well as being a standalone program, it is also used by other KDE programs
such as the Kate editor and KDevelop development environment to provide easy
access to a terminal window. Konsole's features and usage are explained and
illustrated in the Konsole handbook, which can be accessed by browsing to
help:/konsole in Konqueror.
