This patch adds an inheritable option, “font-shaping”, that controls
whether a particle that renders text should enable font-shaping or
not.
The option works similar to the ‘font’ option: one can set it at the
top-level, and it gets inherited down through all modules and to their
particles.
Or, you can set it on a module and it gets inherited to all its
particles, but not to other modules’ particles.
Finally, you can set it on individual particles, in which case it only
applies to them (or “child” particles).
When font-shaping is enabled (the default), the string particle shapes
full text runs using the fcft_rasterize_text_run_utf32() API. In fcft,
this results in HarfBuzz being used to shape the string.
When disabled, the string particle instead uses the simpler
fcft_rasterize_char_utf32() API, which rasterizes individual
characters.
This gives user greater control over the font rendering. One example
is bitmap fonts, which HarfBuzz often doesn’t get right.
Closes#159
Fonts in the configuration may now be a comma separated list of
fonts (all using the fontconfig format). The first font is the primary
font, and the rest are fallback fonts that will be searched, in order.
This allows you to configure the width of each side of the border
individually. border.width can still be used, and will set all four
borders to the same width.
Closes#77
This is an integer that specifies the amount of scrolling that needs
to be accumulated before a wheel-up/down event is emitted.
A higher value means you need to drag your fingers a longer distance
before the event is emitted.
The default is 30.
